"reverse slip",
"strike-slip"
] |
D
|
A strike-slip fault is a dip-slip fault where the dip of the fault plane is vertical. Strike-slip faults result from shear stresses. If you stand with one foot on each side of a strike-slip fault, one side will be moving toward you while the other side moves away from you. If your right foot moves toward you, the fault is known as a right-lateral strike-slip fault. If your left foot moves toward you, the fault is a left-lateral strike-slip fault ( Figure below ).

Note The first controlled chain reaction was achieved on December 2, 1942, in an experiment supervised by Enrico Fermi in a laboratory underneath the football stadium at the University of Chicago. Although fairly simple in theory, an atomic bomb is difficult to produce, in part because uranium-235, the isotope that undergoes fission, makes up only 0.7% of natural uranium; the rest is mostly uranium-238, which does not undergo fission. (Remember that the radioactive process that a nucleus undergoes is characteristic of the isotope. ) To make uranium useful for nuclear reactors, the uranium in uranium-235 must be enriched to about 3%. Enrichment of uranium is a laborious and costly series of physical and chemical separations. To be useful in an atomic bomb, the uranium in uranium-235 must be enriched to 70% or more. At lesser concentrations, the chain reaction cannot sustain itself, so no explosion is produced. Fusion is another nuclear process that can be used to produce energy. In this process, smaller nuclei are combined to make larger nuclei, with an accompanying release of energy. One example is the hydrogen fusion, which makes helium. While the steps of the process are complicated, the net reaction is: 41H → 4He + 2.58 × 1012 J Saylor URL: http://www. saylor. org/books.

Connecting with Patients Dr. Paris often treats several generations of a family over many years. "He's seen us through two births, one operation, multiple earaches, a broken wrist and a recovery from a serious traffic crash," says Jill Farrow, a 43-year-old lawyer whose first visit to Dr. Paris was as a teenager. During the birth of her younger son, Farrow began bleeding badly. Dr. Paris managed to solve the problem in a delicate procedure. "Twenty years ago, she probably would have died," he says. Today, when he performs school sports physical examinations for the Farrow boys, 10 and 11, he is always reminded that lives are changed forever by doctors just doing their jobs. To be a mix of country doc and somewhat adventurer, the 55-year-old family physician moved to Hailey after completing his residency . He hoped to practice medicine there and ski at nearby Sun Valley. Unfortunately, the only job opening was for an emergency-room doctor in Missoula, Montana, 300 miles away. Dr. Paris took it. "I'd ski all day and then drive all night to be in Missoula for a 48-hour shift," he recalls. "I'm lucky to be alive." Knowing he couldn't keep up with his eight-hour commute , he began taking flying lessons. In 1981, Dr. Paris joined a small medical practice in Hailey, a former mining town with a population at the time of 2,109. As Hailey grew in the shadow of Sun Valley's booming popularity, Dr. Paris's own practice expanded to seven physicians, including his wife, Kathryn Woods, who is also a family doctor. They met in 1986 at a certification exam in Denver when, in a room full of men in stodgy suits, Woods arrived wearing a Lycra biking outfit and carrying the front wheel of her bicycle (which she couldn't lock up outside). Dr. Paris asked her out on the spot. In 1989, they married. Why did Dr. Paris move to Hailey?

The Tongue Perhaps you have heard it said that the tongue is the strongest muscle in the body. Those who stake this claim cite its strength proportionate to its size. Although it is difficult to quantify the relative strength of different muscles, it remains indisputable that the tongue is a workhorse, facilitating ingestion, mechanical digestion, chemical digestion (lingual lipase), sensation (of taste, texture, and temperature of food), swallowing, and vocalization. The tongue is attached to the mandible, the styloid processes of the temporal bones, and the hyoid bone. The hyoid is unique in that it only distantly/indirectly articulates with other bones. The tongue is positioned over the floor of the oral cavity. A medial septum extends the entire length of the tongue, dividing it into symmetrical halves. Beneath its mucous membrane covering, each half of the tongue is composed of the same number and type of intrinsic and extrinsic skeletal muscles. The intrinsic muscles (those within the tongue) are the longitudinalis inferior, longitudinalis superior, transversus linguae, and verticalis linguae muscles. These allow you to change the size and shape of your tongue, as well as to stick it out, if you wish. Having such a flexible tongue facilitates both swallowing and speech. As you learned in your study of the muscular system, the extrinsic muscles of the tongue are the mylohyoid, hyoglossus, styloglossus, and genioglossus muscles. These muscles originate outside the tongue and insert into connective tissues within the tongue. The mylohyoid is responsible for raising the tongue, the hyoglossus pulls it down and back, the styloglossus.

B
|
The vertebrate endoskeleton is made of bone and cartilage. Cartilage is a tough, flexible tissue that contains a protein called collagen. Bone is a hard tissue consisting of a collagen framework that is filled in with minerals such as calcium. Bone is less flexible than cartilage but stronger. A bony endoskeleton allows an animal to grow larger and heavier than a cartilage endoskeleton would. Bone also provides more protection for soft tissues and internal organs.

C
|
Enzymes are involved in most of the chemical reactions that take place in organisms. About 4,000 such reactions are known to be catalyzed by enzymes, but the number may be even higher. In animals, an important function of enzymes is to help digest food. Digestive enzymes speed up reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

People who have a fear of ugly insects will want to stay far away from Lake Tawakoni State Park in north Texas, US. A giant spider web was recently found there. The thick web is swarming with millions of little spiders. Stretching across several acres it blankets a number of trees, bushes and even the ground. While the web may make some people nervous, it has become a big attraction for others-especially for unlucky insects. "At first, it was so white that it looked like fairyland," said Donna Garde, the park's manager. "Now it's filled with so many mosquitoes that it's turned a little brown." Most spiders work alone, which is why the discovery of the huge web has caused such a stir. Scientists across the country have been debating its origin. Some spider experts' say the monstrous web may have been weaved by social spiders. Social spiders work together to build larger webs to catch small insects. However, those webs take years to build. Park officials say this web was formed in just a few months. Others say it could be the work of millions of tiny ballooning spiders. These types of spiders 'fly' by throwing out thin threads of silk, which they use to ride air currents . In 2002, a similar giant web made by ballooning spiders was discovered in a field in Canada. Texas entomologist Herbert Pase says the giant web is very unusual. "From what I'm hearing, it could be a once-in-a-life-time event," he said. But John Jackman, an entomologist and professor at Texas A&M University, disagrees. Jackman says he hears reports of similar webs, like the one in Canada, every few years. "There are a lot of folks that don't realize spiders do that," he said. "Until we get some samples sent to us, we won't know what species of spider we're talking about." Park officials expect the web to last until fall when the weather gets cooler. That's when the spiders begin dying off in the park. What is the main reason for scientists' excitement and argument about the giant web?

[
"Most spiders work alone, which makes it hard to understand how the web formed.",
"The huge web causes too many mosquitoes to be killed, which is unbelievable.",
"No similar discoveries have ever been made throughout the world so far.",

Swimming is very popular. People like swimming in summer because water makes people feel cool. If you like swimming but swim in a wrong place, it may not be safe. These years, a lot of people die when they enjoy themselves in water, and most of them are students. Some people are not careful when they are swimming. They often think they swim so well that nothing will happen to them in water. Summer is here again. If you go swimming, don't forget that better swimmers have died in water. They die because they are not careful, not because they cannot swim. So don't get into the water when you are alone. Don't get into the water if there is a " No swimming" sign.

By hit and trial, we put x = 5 and y = 1 so that (3x + 7y) = (3 x 5 + 7 x 1) = 22, which is divisible by 11.
(4x + 6y) = ( 4 x 5 + 6 x 1) = 26, which is not divisible by 11;
(x + y + 4 ) = (5 + 1 + 4) = 10, which is not divisible by 11;
(9x + 4y) = (9 x 5 + 4 x 1) = 49, which is not divisible by 11;
(4x - 9y) = (4 x 5 - 9 x 1) = 11, which is divisible by 11.

Every time you go shopping, the vegetables and fruit look so tempting that you wish you could buy all of them. Some people are lucky and can grow the fruit and vegetables in the gardens that they have. While getting fresh vegetables, they can also achieve great cost cutting. Mushrooms are expensive and can also go bad very quickly. Mushrooms can also be grown easily in a dark environment. In fact it's better than growing other vegetables since you really don't need an outdoor space. A special type of soil that is good for growing mushrooms is easily available. Actually mushrooms aren't even vegetables; they are fungi and for this reason, you don't even require sunlight to grow them. Well how does one go about growing mushrooms? You could always Google "growing mushrooms" and you will find a number of mushroom growing kits available online that area effective and not very expensive either. Mushrooms can be added to any dish that you cook. Simply use them in pizzas, salads and anything that you pretty much fancy. Grow mushrooms in your own house and use them whenever you want. Fresh mushrooms are tastier than the ones that are stored in your refrigerator. If you have had a really good crop of mushrooms, then you can even store them. Ideally you should use the white variety of the mushrooms. Simply pick them, slice them and put them on a cookie sheet in a freezer. When they area frozen, just put them in a zip lock and you can use them when you want to. They give a really great taste to the dish that you are making. Thaw them before you use them. You should try growing mushrooms, since it's cost-effective. Furthermore, you can eat the fresh mushrooms any time that you want. Mushrooms are different from other vegetables in that _ .

4.4 Muscle Tissue and Motion The three types of muscle cells are skeletal, cardiac, and smooth. Their morphologies match their specific functions in the body. Skeletal muscle is voluntary and responds to conscious stimuli. The cells are striated and multinucleated appearing as long, unbranched cylinders. Cardiac muscle is involuntary and found only in the heart. Each cell is striated with a single nucleus and they attach to one another to form long fibers. Cells are attached to one another at intercalated disks. The cells are interconnected physically and electrochemically to act as a syncytium. Cardiac muscle cells contract autonomously and involuntarily. Smooth muscle is involuntary. Each cell is a spindle-shaped fiber and contains a single nucleus. No striations are evident because the actin and myosin filaments do not align in the cytoplasm.

The United States government wants to know what the public thinks about its findings on the safety of cloned animals. The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An F.D.A. official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually , the agency says, their offspring are safe to eat as well. But research on cloned sheep is limited. So the F.D.A. proposes that sheep clones not be used for human food. The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents. The agency says it must receive comments by April second. The F.D.A. seemed ready to act several years ago, but an advisory committee called for more research. For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals. Clones are still rare. They cost a lot and are difficult to produce. The F.D.A. says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities. Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning. Cloning differs from genetic engineering. A cell taken from a so-called donor animals is grown into an embryo in the laboratory. Next, the embryo is placed into the uterus of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born. From the passage we know that_.

Tea vs Coffee Tea and coffee are two of the most widely consumed drinks in the United States. With popularity and interest in tea continuing to grow in recent years, many consumers have recently considered making the switch from coffee to tea, if they have not done so already. All the buzz surrounding tea and coffee may have you wondering, what are the differences? As it turns out, the differences are many and varied. In the US, interest in tea ranges from coast to coast with the highest in Hawaii and California but stretching to the eastern states of Vermont and New York. On the other hand, the highest interest in coffee tends to be concentrated more in the north and western regions , with the highest search volumes appearing in the states of Hawaii, Washington and Minnesota. Differences between tea and coffee also vary in origin and production. All tea comes from the harvested leaves of the Camellia sinensis plant, while there are about 60 different species of coffee plants. Production of tea is quicker and more efficient: Camellia sinensis plants only need to grow for three years before they are ready to process; coffee plants take up to five years. Perhaps the most concerning issue consumers have when considering making the switch to tea is the question of caffeine. The good news is, when it comes to tea and caffeine, there is something for everyone. Unlike coffee, which typically only comes in decaffeinated and regular, there are several varieties of tea available, based on caffeine preference. From herbal teas that are naturally free of caffeine, to high quality green and black teas that offer less than half the caffeine of coffee, to high caffeine teas such as our specially formulated HiCAF(r) blends that contain slightly more caffeine than a cup of coffee, there is a variety sure to suit your needs. As an added bonus, the lower acidity levels in tea tend to be gentler on the stomach for a more comforting pick-me-up. So what is the answer, coffee or tea? If you are looking for the most healthful benefit possible, tea is probably the winner. They say a picture is worth a thousand words. If, like many Americans, the rising popularity in tea has your interest piqued, the images below will help to clearly spell out the differences between tea and coffee. According to the passage, which of the following contains the least caffeine?

Earth is not the only active planetary body in the solar system. Io, one of Jupiter’s moons, is home to fantastic volcanic eruptions. Volcanism is much hotter than on Earth. Lava curtains and fountains are common. In this color image, the Galileo spacecraft spotted two volcanic plumes. One is spewing high above the planet on the horizon. The second is near he boundary between day and night. Besides being hotter than Earth’s volcanism, eruptions on Io have a different composition. They are mostly sulfur!.

Jane Odd is the owner of Oddly Odd Book Store. Jane Odd loves odd things, but her book seller only sells books in even numbers. If there are an even number of books in the book store (b = an even number), and Jane divides the books into groups of 18 books, which results in an odd number of groupings (b/18 = an odd number). Now, if Jane doubles the number of books in the store, how can she divide the books up to keep an odd number of groupings (b^2/X = an odd number)?

Divisible by 2 (Parity Mathematics) states: an even number is an integer of the form n = 2k, where k is an integer; an odd number is an integer of the form n = 2k + 1.
Since a is an even number, a = 2k, a^2 = 4k^2 = (2)(2)(k)^2, and a/18 is an odd number 2k/18.
18 = (2)(9). Now (2k)/((2)(9)) = k/9. So, we are looking for a (2)(2) factor in the denominator.
Factors are:
12 = (2)(2)(3)
18 = (2)(9)
9 = (3)(3)
6 = (2)(3)
2 = (2)
So, 12 has more than 1 (2).

Cytokinesis is the final step in cell division. It often occurs concurrently with telophase, though it is a separate process. Cytokinesis ( Figure below ) differs between plant and animal cells. In animal cells, the plasma membrane pinches inward along the cell’s equator until two cells are formed. Specifically, a cleavage furrow containing a contractile ring develops in approximately the middle of the cell (similar to the position of the metaphase plate), essentially pinching off the two nuclei and forming separate cells. In plant cells, a cell plate forms along the cells equator. A new membrane grows along each side of the cell plate, with a new cell wall forming on the outside of each new membrane.

Not everyone can afford their own vehicle,and with the high demands of consumers and incredible expectations of today g leading engineers,public transportation needs all the improvement it can get. Nowadays,there aren't many comfortable alternatives to owning your own car,unless you're happy with inaccessible and expensive rental Pars.To fight against this.the City Car appeared and it's stackable electric car with room for two.Saving the burden of paying for gas and spending times searching for parking in a crowded city, the City Car would be an ideal and inexpensive form of transportation with easy storage. But for those of you that want to stick to trains on tracks,China's 3 D Express Coach is the answer.Unlike trains that must run far from shopping areas or even stay underground because there's simply no room for tracks,the Express Coach runs on rails positioned above the freeway.With more Express Coaches, public transportation would be more time-efficient and energy-efficient. Have you heard of the Nano car? The Tata Nano from India is ten percent of the cost of most new cars.Because of its current lack of an airbag and difficult access to the trunk,the Nano does not meet certain safety standards in other countries but after improvements are made,you may be able to buy a new car for less than$3.000 and enjoys its fit in a motorcycle parking space. The pioneer of hybrid cars,the Toyota Prius,is the shining model of the alternatively fueled vehicle.Due to the Prius' great success,the Lexus RX 450h,Honda Insight and Ford Fusion Hybrid quickly followed.A hybrid car alternates gas and electric power,but contains a complete electric motor.When you drive a hybrid,it's mostly run electrically,but some gasoline powers the generator . Cars like these are no longer imaginary.They are being planned and built,making them not just a fantasy anymore. A hybrid car is a car that _ .

Autoimmune diseases occur when the immune system fails to recognize the body’s own molecules as “self,” or belonging to the person. Instead, it attacks body cells as though they were dangerous pathogens. There are more than 80 known autoimmune diseases. Recall that regulatory T cells help regulate the immune system. When autoimmune disorders occur, these regulatory T cells fail in their function. This results in damage to various organs and tissues. The type of autoimmune disorder depends on the type of body tissue that is affected.

Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true. People who studied plants have found out that plants carry a small electrical charge . It is possible to measure this charge with a small piece of equipment called "galvanometer". The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened. A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects . Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room. Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them. The scientist called Sauvin _ .

Recently I was asked,"Are we anywhere near the day when you can climb into a car on Long Island, program it to take you to your niece's house in Chicago, hit enter, and after the first hundred yards, once you hit a main road, the car takes over automatically and you just sit back and enjoy the ride?" It is a question I worry. But I had to answer truthfully:"Absolutely. We are without a doubt near that day."Look, we're already doing it with airplanes. Northrop Grumman's Global Hawk takes off at an air base in the U.S., climbs to 50,000 feet, flies to Australia, and lands at an Australian air base, where there is a grandstand filled with military officials=with no human pilot. The necessary technology is already here. We have radar technology that can be tied to cruise control and brakes, which automatically adjusts your speed based on following distance and preprogrammed settings. It's still a little bit raw, but it does work great. The technology can allow cars and trucks to follow each other in very closely spaced roads. GPS can also change speed with location. Let's say you're in a state with a 75-mph limit and you cross into a state with a 65-mph limit. GPS knows that and adjust your speed accordingly. It's not out of the question to imagine that someday soon you'll be able to start the car, make proper settings, then turn the front seats around and play cards and eat lunch as if you're riding on a train. All in perfect comfort and safety, all the way to that niece's place inprefix = st1 /Chicago.

Modern Amphibians Amphibia comprises an estimated 6,770 extant species that inhabit tropical and temperate regions around the world. Amphibians can be divided into three clades: Urodela (“tailed-ones”), the salamanders; Anura (“tail-less ones”), the frogs; and Apoda (“legless ones”), the caecilians. Urodela: Salamanders Salamanders are amphibians that belong to the order Urodela. Living salamanders (Figure 29.16) include approximately 620 species, some of which are aquatic, other terrestrial, and some that live on land only as adults. Adult salamanders usually have a generalized tetrapod body plan with four limbs and a tail. They move by bending their bodies from side to side, called lateral undulation, in a fish-like manner while “walking” their arms and legs fore and aft. It is thought that their gait is similar to that used by early tetrapods. Respiration differs among different species. The majority of salamanders are lungless, and respiration occurs through the skin or through external gills. Some terrestrial salamanders have primitive lungs; a few species have both gills and lungs. Unlike frogs, virtually all salamanders rely on internal fertilization of the eggs. The only male amphibians that possess copulatory structures are the caecilians, so fertilization among salamanders typically involves an elaborate and often prolonged courtship. Such a courtship allows the successful transfer of sperm from male to female via a spermatophore. Development in many of the most highly evolved salamanders, which are fully terrestrial, occurs during a prolonged egg stage, with the eggs guarded by the mother. During this time, the gilled larval stage is found only within the egg capsule, with the gills being resorbed, and metamorphosis being completed, before hatching. Hatchlings thus resemble tiny adults.

8x + 8y = 11y
8x – 3y =0 ----(ii)
Adding (i) & (ii), we get : 10 x = 30 or x = 3.
Put x = 3 in (i), we get : y = 8

Some of the things a cellphone can do for you will be available this year: Surf at speed Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150. Listen as you go The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens. Say cheese Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video. Portable TV You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee. The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator...

This prompt is worded in an odd way, but essentially tells us that the probability of lasso-ing a cow is 1/2. The question asks for the probability of lasso-ing a cow AT LEAST ONCE in 5 attempts.
When it comes to probability questions, there are only 2 things that you can calculate: what you WANT to have happen OR what you DON'T WANT to have happen. Those two fractions will always add up to 1. Sometimes it's much easier to calculate what you DON'T WANT and then subtract that fraction from 1 (which will give you the probability of what you DO want).
Here, the work that would be required to calculate 1, 2, 3, 4, and 5 lasso-ings of a cow would take some time and effort. It's far easier to calculate what we DON'T WANT (0 lasso-ings) and subtract that fraction from 1.
The probability of NOT lasso-ing the cow on 5 attempts is:
(1/2)(1/2)(1/2)(1/2)(1/2) = 1/32
1 - 1/32 = 31/32
The probability of lasso-ing a cow AT LEAST ONCE in 5 attempts is 31/32

Once there was a fish who had lived his whole life in his bowl. He often got bored and wished to see the rest of the world, but because he was a fish, he couldn't leave the water. So one day he made a special fish suit that would allow him to walk on land and breathe air like humans. He knew this would change his life, and make him rich, but first he would have to test it out. He put the suit on and leaped from the bowl that until now had been his whole world. The suit worked! Now he could go where he wanted. First he went to the kitchen of the house. There he saw a parrot eating a cracker. Second he went outside to the yard. He saw squirrels there running around looking for food. Third he went to the barn in the field. He saw a mommy cow. She was teaching her calf how to run. Finally he went to forest where he saw more trees than he had ever seen in his whole life. But after all this he was tired, and made up his mind to go back to his home in the bowl. It was a lot of work trying to see the world. He took off the special suit and splashed back into the water. His suit had passed the test and he was very happy, but he had made up his mind that his bowl was the place for him. Where had the fish lived his whole life?

The brain is said to contain gray matter, while what related structure contains white matter separated into columns?
|
[
"amygdala",
"spinal cord",
"brain stem",
"orbital lobe"
] |
B
|
White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tracts—the latter carrying motor commands down from the brain to the spinal cord to control output to the periphery.

In late summer or early fall the large, yellow seed heads of sunflowers will be ripening. If gardeners can keep off the birds and other wildlife trying to eat the seeds, they can have a large harvest. The bright yellow blooms will make a rainbow garden, brightening up any space. However, planting the sunflower seeds is a skilled job. Plant seeds no deeper than the full length of itself. Smaller sized sunflowers can be spaced a foot apart. Larger varieties will need to be spaced as far apart as three feet. This allows ripe plants enough space for the seed heads to ripen without knocking the ripe seeds off before gardeners have a chance to harvest them. Most sunflower seeds, especially those with eatable seeds, are large enough to handle without the need for seed sorters. This is why sunflowers make an excellent choice for a children's garden as well. Gardeners will want to mix plenty of soil fertilizers into the ground as sunflowers tend to be heavy feeders. Sunflowers can be slow starters and the tiny new plants don't seem to grow very rapidly. Gardeners should protect the new plants as they begin to grow. Once they get going, sunflowers are able to _ many weeds, making them easier to grow in the home vegetable garden than many other plants. Most pests and diseases are not a bother to the sunflower, however, more than one gardener has said that their lovely looking plants were destroyed overnight by hungry squirrels, mice or birds. To preserve their harvest, gardeners can cover the ripening seed head with stockings or net cloth to help keep the destroyers off the seeds. Planting sunflower seeds is easy and can help even the smallest gardener feel successful in their gardening attempts. Why should enough space be left between sunflowers?

Electronic books have changed the way many people read for pleasure. Now online textbooks are changing the way some students learn and some teachers teach. More than one hundred seventy-five thousand students attend the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed from printed to electronic textbooks in their social studies classes. Luke Rosa is a history teacher at Falls Church High School. His students work on laptop computers at school. He explains the idea to them this way. "I mean, it's just like a regular textbook, except it's got it all online." Peter Noonan, an assistant superintendent of schools, said, "The world's changing. And the online textbooks can change right along with the events that are happening." Digital books also cost less than printed textbooks, he said. A student named Melanie Reuter said, "I don't have to carry a textbook around, so that's nice." But another student said, "I don't like it because the Internet sometimes doesn't work." Students also need access to the Internet when they are not at school. About ten percent of students in Fairfax Country do not have a computer or online access at home. Public libraries in the country have free Internet. There are also after-school computer labs as well as computer clubhouse supported by the country. Middle school student Slieman Hakim is happy about that. He said, "My family only has one computer; my sister and I both do our homework on it. So I come here to do my homework. It's good." Other school systems in the area are also considering online textbooks. According to the passage, one of the disadvantages of digital textbooks is that _ .

The diversity of alleles and genotypes within a population is known as genetic what?

Before Darwinian evolution became the prevailing theory of the field, French naturalist Jean-Baptiste Lamarck theorized that acquired traits could, in fact, be inherited; while this hypothesis has largely been unsupported, scientists have recently begun to realize that Lamarck was not completely wrong. Visit this site (http://openstaxcollege. org/l/epigenetic) to learn more. Heritability is the fraction of phenotype variation that can be attributed to genetic differences, or genetic variance, among individuals in a population. The greater the hereditability of a population’s phenotypic variation, the more susceptible it is to the evolutionary forces that act on heritable variation. The diversity of alleles and genotypes within a population is called genetic variance. When scientists are involved in the breeding of a species, such as with animals in zoos and nature preserves, they try to increase a population’s genetic variance to preserve as much of the phenotypic diversity as they can. This also helps reduce the risks associated with inbreeding, the mating of closely related individuals, which can have the undesirable effect of bringing together deleterious recessive mutations that can cause abnormalities and susceptibility to disease. For example, a disease that is caused by a rare, recessive allele might exist in a population, but it will only manifest itself when an individual carries two copies of the allele. Because the allele is rare in a normal, healthy population with unrestricted habitat, the chance that two carriers will mate is low, and even then, only 25 percent of their offspring will inherit the disease allele from both parents. While it is likely to happen at some point, it will not happen frequently enough for natural selection to be able to swiftly eliminate the allele from the population, and as a result, the allele will be maintained at low levels in the gene pool. However, if a family of carriers begins to interbreed with each other, this will dramatically increase the likelihood of two carriers mating and eventually producing diseased offspring, a phenomenon known as inbreeding depression. Changes in allele frequencies that are identified in a population can shed light on how it is evolving. In addition to natural selection, there are other evolutionary forces that could be in play: genetic drift, gene flow, mutation, nonrandom mating, and environmental variances.

Zebras cannot clap. However, one weekend a magic clown wiggled his nose and said a few magical words and a zebra could clap. This zebra lived in a zoo with many other zebras. This zebra's name was John, John the Zebra. John was so excited that he could clap. He tried to clap as much as he could. He had trouble understanding when and what to clap. He would clap at things that were sad and things that were happy. He clapped when he was excited and when he was scared. He even clapped that he could clap. After a couple of weeks, his friend Sam was getting annoyed with John. He said "John, I know you like clapping but I am beginning to be annoyed by your clapping." John said he was sorry, but that Sam did not understand how special it was to be the first Zebra that could clap. A few more weeks went by and the same Magical clown came by John's zoo. He looked at John, who was clapping his heart out, and wiggled his nose and said some different magical words. Suddenly, John could not clap any more. And that month was first and only time a zebra could clap. How long could John clap?

Paleontology, another branch of biology, uses fossils to study life’s history (Figure 1.20). Zoology and botany are the study of animals and plants, respectively. Biologists can also specialize as biotechnologists, ecologists, or physiologists, to name just a few areas. This is just a small sample of the many fields that biologists can pursue. Biology is the culmination of the achievements of the natural sciences from their inception to today. Excitingly, it is the cradle of emerging sciences, such as the biology of brain activity, genetic engineering of custom organisms, and the biology of evolution that uses the laboratory tools of molecular biology to retrace the earliest stages of life on earth. A scan of news headlines—whether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified food—demonstrates the way biology is active in and important to our everyday world.
