B. breaking and reforming
Stereoisomers Molecules with the same connectivity but different arrangements of the atoms in space are called stereoisomers. There are two types of stereoisomers: geometric and optical. Geometric isomers differ in the relative position(s) of substituents in a rigid molecule. (For more information on stereoisomers, see Chapter 23 "The ", Section 23.4 "Coordination Compounds". ) Simple rotation about a C–C σ bond in an alkene, for example, cannot occur because of the presence of the π bond. The substituents are therefore rigidly locked into a particular spatial arrangement (part (a) in Figure 2.16 "Some Simple (a) Alkenes, (b) Alkynes, and (c) Cyclic Hydrocarbons"). Thus a carbon–carbon multiple bond, or in some cases a ring, prevents one geometric isomer from being readily converted to the other. The members of an isomeric pair are identified as either cis or trans, and interconversion between the two forms requires breaking and reforming one or more bonds. Because their structural difference causes them to have different physical and chemical properties, cis and trans isomers are actually two distinct chemical compounds.

A telecom service provider engages male and female operators for answering 1000 calls per day. A male operator can handle 40 calls per day whereas a female operator can handle 50 calls per day. The male and the female operators get a fixed wage of Rs. 250 and Rs. 300 per day respectively. In addition, a male operator gets Rs. 15 per call he answers and female operator gets Rs. 10 per call she answers. To minimize the total cost, how many male operators should the service provider employ assuming he has to employ more than 7 of the 12 female operators available for the job?
A. 15 B. 14 C. 12 D. 10 E. 11
D. 10
Explanation : There are two equations to be formed 40m + 50f = 1000. 250m + 300f + 40 x 15m + 50 x 10f = A. 850m + 8000f = A. m and f are the number of males and females. A is the amount paid by the employer. Then the possible value of f = 8,9,10,11,12. Iif f= 8, M =15. If f = 9,10,11 then m will not be an integer while f =12 then m will be 10. By putting f = 8 and m=15 , A = 18800. when f =12 and m= 10 then A = 18100. Hence, the number of males is 10. Answer : D

The Man of Many Secrets Harry Houdini was one of the greatest American entertainers in the theater this century.He was a man famous for his escapes--from prison cells,from wooden boxes floating in rivers,from locked tanks full of water.He appeared in theaters all over Europe and America.Crowds came to see the great Houdini and his "magic"tricks. 0f course,his secret was not magic,or supernatural powers.It was simply strength.He had ability to move his toes as well as to move his fingers.He could move his body into almost any position he wanted. Houdini started working in the entertainment world when he was 17,in 1891.He and his brother Theo performed card tricks in a New York club.They called themselves the Houdini brothers.When Harry married in 1894,he and his wife Bess worked together as magician and assistant,but for a long time they were not successful.Then Harty performed his first prison escape,in Chicago in 1898.Harry persuaded a detective to let him try to escape from the prison,and he invited the local newspaperman to watch.It was the publicity that came from this that started Harry Houdini's success. Harry had fingers trained to escape from handcuffs and toes trained to escape from ankle chains,but his biggest secret was how he unlocked the prison doors.Every time he went into the prison cell,Bess gave him a kiss for good luck--and a small skeleton key,which is a key that fits many locks passed quickly from her mouth to his. Harry used these prison escapes to build his fame.He arranged to escape from the local jail of every town he visited.In the afternoon the people of the town would read about it in their local newspapers.and in the evening every seat in the local theater would be full.What was the result? Worldwide fame,and a name remembered today. According to the passage,Houdini's success in prison escapes depends on _ . A. his magic tricks and inhuman powers B. his special tricks and a skeleton key C. his unusual ability and skeleton key D. his inhuman talents and magic tricks

Jeffrey Bezos, the founder, president and chairman of the board of Amazon. com, was born in Albuquerque, New Mexico. His mother's ancestors were early settlers in Texas, and over the generations had acquired a 25,000 acre farm at Cotulla. Jeffrey spent most summers of his youth working with his grandfather on their farm. Jeffrey showed intense and varied scientific interests at an early age. He set up an electric alarm to keep his younger sisters and brothers out of his room and changed his parents' garage into a laboratory for his science projects. After he graduated from Princeton University with a degree in computer science and electrical engineering, Jeffrey Bezos found employment on Wall Street, where computer science was increasingly in demand to study market trends. He rose quickly, becoming a senior vice president, and looked forward to a bright career in finance, when he made a discovery that changed his life, and the course of business history. In 1994, there was still no Internet commerce to speak of. One day that spring, Jeffrey Bezos observed that Internet usage was increasing by 2,300 percent a year. He saw an opportunity for a new circle of commerce, and immediately began considering the possibilities. Bezos founded Amazon. com in 1994, setting up the original company in his garage. The company was called Amazon for the seemingly endless South American river with its numberless branches. It started as an online bookstore but soon diversified to all kinds of products. His work with Amazon eventually led him to become one of the most excellent dot-com entrepreneurs. He was named Time magazine's Person of the Year in 1999. In 2008, he was selected by U. S. News & World Report as one of America's Best Leaders. Bezos's Amazon has become "the Earth's biggest anything store". Amazon. com is now called "one of the smartest strategies in business history. Today Jeffrey Bezos lives North of Seattle and is increasingly concerned with charity activities. "Giving away money takes as much attention as building a successful company," he has said. In his childhood, Bezos _ . A. had to work with parents on their farm all day long B. showed great interest in science C. didn't get along well with his brothers and sisters D. wanted to become a businessman
B. showed great interest in science

London-Lazy students can now give up on work altogether as two Oxford University students have made scores of A-grade essays on the website for students to copy. The essays are on the new website, "revise.it" The website includes an "EssayLab" designed to make cheating as effective and effortless as possible. Its homepage announces to surfers : "The revise.it EssayLab is a bank of hundreds of A-Level essays covering popular topics." "Next time you are asked to write an essay, why not see what we have on the subject-if you are in a lazy state of mind you can even use our guide to writing the essays and then just hand them in." Nick Rose and Jordan Mayo, both 19 and first from Manchester, spent much of their first year as students at the university setting up the website. There is no charge for downloading the essays. "I have never been very good at essay writing," Rose admitted. "We don't see essay bank as a cheating way. It's a surprising valuable resource. You can learn a lot by reading other people's work on the subject." Among other tips, the website suggests inventing important speeches to give essays extra weight: "Popular people to quote are Douglass Hurd or Disraeli." Hurd was a foreign secretary in the 1980s and Disraeli was a 19 century prime minister. Teachers are expressing their opinions by e-mail that they are angry about the website that "encourages students to cheat", but students disagree. According to Rose: "Exams are a fight. It's us against them." It can be inferred from this passage that _ . A. students who visit the website "revise. it" are all lazy B. students in Oxford University are all lazy C. websites in Oxford University are all set up by students D. websites can provide people with different kinds of information
D. websites can provide people with different kinds of information

Dear Ms. Wang, I am writing to inform you of some arrangements about my composition course and Latin course next year. I've decided to re-establish the 5-paragraph essay as the goal for the composition course. I interviewed some of my former students and they all agreed that being able to write critically and continuouslywas important to them. So next academic year, Term 1 will be like always: sentences to paragraphing. And Term 2 will work toward the 5-paragraph essay. The final 3 weeks of Term 2 will be reserved tointroduce writing for TOEFL and CEE. By that time, if the students have done their job correctly, then they should be able to write quite well. As for the Latin course, I will post notices around campus next week so that the students will understand what's on offer before I actually introduce the course. A number of students already emailed me about the course. I am sure you don't understand what a big deal our opening this program at our school is. People around the world are interested in what we plan to do. There are many rewards available to the students who succeed in the course. Please share what I have said with the administration. I want them to understand the importance of this course. The reason I have contacted these colleagues (actually Oxford contacted me) isthatI have confidence in our students and in myself. I know that when those professors meet our students and hear them speaking and reading Latin, they are going to be amazed. It will open all sorts of doors for students that they never even thought of knocking on. Well, that's it for now. I'll see you soon. Yours, Edward Johnson According to the letter, what will Edward teach about writing in Term 1? A. Critical thinking. B. 5-paragraph essay. C. Sentences to paragraphing. D. Writing for TOEFL and CEE.

People who do not get enough vitamin A in their diet may develop night blindness.But in the developing world a lack of vitamin A causes much more serious harm to children.The World Health Organization links the lack of vitamin A to as many as 250.000 child deaths every year. One excellent source of vitamin A is found in sweet potatoes with orange flesh.Orange sweet potatoes contain high levels of beta-carotene ,which our body can change into vitamin A. Experts say orange sweet potatoes specially bred (,) for growing conditions in Africa could help solve the lack of vitamin A there. But, first, more people will need to be persuaded to eat them. Jan Low with the International Potato Center, a research organization says the sweet potato needs a better image in Africa. Jan Low says,... We do have an image problem with sweet potato in general in sub-Saharan Africa. It is seen as a crop of the poor. " Ms Low explains that sweet potatoes are mainly grown by poor women to feed their families in case another crop fails. The sweet potatoes commonly grown if Africa have white or yellow flesh. But, more importantly, they are low in vitamin A. Jan Low took part in a project to study how best to market orange sweet potatoes to Africans.She worked on an information campaign in Mozambique and Uganda.The campaign included radio messages about the nutritional benefits of the orange sweet potato.They advertised its ability to" fight diseases, make you strong, clear your skin and make you look healthy." In areas without radio, the campaigners spread the message through community theater.The performances included singing, dancing and storytelling.And everywhere they went, the campaigners wore orange T-shirts and hats.They even drove orange vehicles.Jan Low says the color1 made it easier to gain public attention. Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization. He points to efforts in the past to increase the popularity of other nutritious crops. He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat.But Mr.Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa. For one thing, except for the color1, the vegetable is similar to what people already use. Jan Low works for_. A. the World Health Organization B. the International Potato Center C. the government of Mozambique and Uganda D. the United Nations Food and Agriculture organization
B. the International Potato Center

A. 1858
In 1858, after using microscopes much better than Hooke’s first microscope, Rudolf Virchow developed the hypothesis that cells only come from other cells. For example, bacteria, which are single-celled organisms, divide in half (after they grow some) to make new bacteria. In the same way, your body makes new cells by dividing the cells you already have. In all cases, cells only come from cells that have existed before. This idea led to the development of one of the most important theories in biology, the cell theory .

Loren Gladstone of Toronto is 58, but thinking over how to bequeath his digital property . Doing the paperwork after his parents' death was a challenge. "When my time comes, I wonder if my children will even know what paper is," he says. As a software developer, his virtual property is both valuable and vital to his business. That reflects a problem. Online lives have increasing economic and emotional value. But testamentary laws offer confusing and incomplete ways of bequeathing and inheriting them. Digital property may include software, websites, downloaded content, online gaming identities, social-media accounts and even e-mails. In Britain alone holdings of digital music may be worth over PS9 billion ($14 billion). A fifth of respondents to a Chinese local-newspaper survey said they had over 5,000 yuan($790) of digital property. And value does not lie only in money."Anyone with kids under 14 years old probably has two prints of them and the rest are in online galleries,"says Nathan Lustig of Entrustet, a company that helps people manage digital property. Service providers have different rules--and few state them clearly in their terms and conditions. Many give users a personal right to use an account, but nobody else, even after death. Facebook allows relatives to close an account or turn it into a memorial page. Gmail (run by Google) will provide copies of e-mails to an executor . Music downloaded via iTunes is held under a license which can be abolished on death. Apple declined to comment on the record on this or other policies. All e-mail and data on its iCloud service are deleted on the death of the owner. This has led to cases to court in America. In 2004 the family of Justin Ellsworth, an army man killed in Iraq, took Yahoo! to court in Michigan to get copies of his e-mails. This year, a court in Oregon ruled that another American mother whose son had died could use her dead son's password to enter his Facebook account for a short period. Now five American states have made laws giving executors control over the social-networking accounts of dead users. But this raises the subject of privacy. Passing music on is one thing; not everyone may want their relatives to read their e-mails. Colin Pearson, a London-based lawyer, says access should come only with a clear provision in a will. But laws, wills and password safes may be contrary to the providers' terms of service, especially when the executor is in one country and the data in another. Headaches for the living and lots of lovely work for lawyers. Why does Loren begin to think over how to bequeath his digital property at the age of 58? A. Because he is afraid his children don't know what paper is. B. Because there's no complete law dealing with digital property. C. Because his digital property is of great value and importance. D. Because he is worried his children will be taken to court.
B. Because there's no complete law dealing with digital property.

What heisenberg principle imposes ultimate limits on what is knowable in science? A. uncertainty principle B. certainty principle C. impossibility principle D. vacuum principle
A. uncertainty principle
The value of ħ is not large, so the uncertainty in the position or momentum of a macroscopic object like a baseball is too insignificant to observe. However, the mass of a microscopic object such as an electron is small enough that the uncertainty can be large and significant. It should be noted that Heisenberg’s uncertainty principle is not just limited to uncertainties in position and momentum, but it also links other dynamical variables. For example, when an atom absorbs a photon and makes a transition from one energy state to another, the uncertainty in the energy and the uncertainty in the time required for the transition are similarly related, as ΔE Δt ≥ ℏ . As will be discussed later, even the vector components of angular 2 momentum cannot all be specified exactly simultaneously. Heisenberg’s principle imposes ultimate limits on what is knowable in science. The uncertainty principle can be shown to be a consequence of wave–particle duality, which lies at the heart of what distinguishes modern quantum theory from classical mechanics. Recall that the equations of motion obtained from classical mechanics are trajectories where, at any given instant in time, both the position and the momentum of a particle can be determined exactly. Heisenberg’s uncertainty principle implies that such a view is untenable in the microscopic domain and that there are fundamental limitations governing the motion of quantum particles. This does not mean that microscopic particles do not move in trajectories, it is just that measurements of trajectories are limited in their precision. In the realm of quantum mechanics, measurements introduce changes into the system that is being observed.

She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her booth, passers-by often can hear her talking on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world. According to the passage we know that _ . A. Valerie looks like a real beautiful woman B. Valerie can do whatever a human receptionist can't C. Visitors can have a conversation with Valerie D. Valerie doesn't understand of the visitors' questions sometimes

It was a rainy day and James wanted to play. If he went outside to play, he would get wet. James' mother told him not to get wet because he might catch a cold. James went out to play, anyway. Outside, the cool rain kept falling. There were no other children for James to play with. The other children were all playing inside, where it was warm and dry. James found a puddle that had appeared in the mud. He found a piece of wood and pretended it was a turtle. He put the wooden turtle in the puddle and watched it float in a circle. This was not very fun. After one hour, James went back inside. When James went inside, he found his mother waiting. She had her hands on her hips and a serious look on her face.

Chinese tourists prefer hotels and restaurants that offer free Wi-Fi when traveling abroad. Most Chinese tourists instantly update their social networks using their mobile phones. They send photos and short videos to friends and family when traveling abroad. About 10 percent of outbound Chinese tourists get expensive marring charges by using 3G-powered smart phones. About 90 percent of Chinese travelers consider Wi-Fi _ when traveling abroad They often use phone apps to create travel routes and book hotels, which requires large data flows that can be expensive without Wi-Fi But free Wi-Fi is not always available, even in regions with advanced telecnrnmunications,such as the United States and Europe. Portable Wi-Fi costs 15 -50 yuan a day,depending on the country. Ifs cheaper in South Korea,Japan and Thailand. The Wi-Fi services increase rapidly thanks to reasonable pricing and smooth surfing Thus, a growing number of travel agencies begin to offer increasingly diverse Wi-Fi services. A travel website Ctrip leases Wi-Fi transmitters that offer unlimited data for about 20 yuan a day on average in more than 100 countries. It plans to make mobile Wi-Fi an important part of its business model. Another travel website Tumiu also launched a Wi-Fi phone service in 2013. More than 100, 000 people used the service in 2014.

For each positive integer,the quantitySn is defined such thatSn+2=(Sn)^4 -S(n+1).in addition ,S2=1.then which of the following must be true.

C. c) ifS1=-1thenS4 is also equal to-1.
Since all the answers include S4, let's start from there. S4=S2^2-S3 S3=S1^2-S2 Substituting S3 into the first equation we get: S4=S2^2-(S1^2-S2) Since S2=1 S4=1-(S1^2-1) S4=2-S1^2 We need S1^2 in order to calculate S4. E) provides S1 and from there we can calculate S4: S4=2-(-3)^2 S4=-7 Correct. As a side note, I would be very careful with answers in the formif S4=x then S1=y(such as option D ), as we are dealing with S1^2 (not S1), S1 can have two different values and it can not be determined for sure which root is the right answer. For example: If S4=-7 then S1=3 : if we substitute S4 with - 7 we get: -7=2-S1^2 S1^2=9 now S1 can be +/-3 !! C

When the maximum amount of solute has been dissolved in a given amount of solvent, we say that the solution is what? A. blended B. empty C. used D. saturated
D. saturated
When the maximum amount of solute has been dissolved in a given amount of solvent, we say that the solution is saturated with solute. When less than the maximum amount of solute is dissolved in a given amount of solute, the solution is unsaturated. These terms are also qualitative terms because each solute has its own solubility. A solution of 0.00019 g of AgCl per 100 g of H2O may be saturated, but with so little solute dissolved, it is also rather dilute. A solution of 36.1 g of NaCl in 100 g of H2O is also saturated but rather concentrated. Ideally, we need more precise ways of specifying the amount of solute in a solution. We will introduce such ways in Section 11.2 "Quantitative Units of Concentration". In some circumstances, it is possible to dissolve more than the maximum amount of a solute in a solution. Usually, this happens by heating the solvent, dissolving more solute than would normally dissolve at regular temperatures, and letting the solution cool down slowly and carefully. Such solutions are called supersaturated solutions and are not stable; given an opportunity (such as dropping a crystal of solute in the solution), the excess solute will precipitate from the solution. It should be obvious that some solutes dissolve in certain solvents but not others. NaCl, for example, dissolves in water but not in vegetable oil. Beeswax dissolves in liquid hexane but not water. What is it that makes a solute soluble in some solvents but not others? The answer is intermolecular interactions. The intermolecular interactions include London dispersion forces, dipole-dipole interactions, and hydrogen bonding (as described in Chapter 10 "Solids and Liquids"). From experimental studies, it has been determined that if molecules of a solute experience the Saylor URL: http://www. saylor. org/books.

What occurs when two opposite charges are separated by some amount of distance? A. dipole B. particle C. diffusion D. radioactivity
A. dipole
A dipole occurs when two opposite charges are separated by some amount of distance. We have already seen dipoles in the form of polar bonds. For example, each O-H bond in water is an example of a dipole; the partial positive charge on hydrogen is separated from the partial negative charge on oxygen by the length of the bond. A molecular dipole is the geometric sum of all the individual bond dipoles in a molecule. In order for a molecule to have a dipole, it must have at least one polar bond. However, not all molecules with polar bonds have an overall molecular dipole. Sometimes the dipoles within a molecule will effectively cancel each other out, giving a zero net molecular dipole. This is often seen in symmetrical molecules.

What are the cells or structures that detect sensations? A. proteins B. hormones C. membranes D. receptors
D. receptors
14.1 | Sensory Perception By the end of this section, you will be able to: • Describe different types of sensory receptors • Describe the structures responsible for the special senses of taste, smell, hearing, balance, and vision • Distinguish how different tastes are transduced • Describe the means of mechanoreception for hearing and balance • List the supporting structures around the eye and describe the structure of the eyeball • Describe the processes of phototransduction A major role of sensory receptors is to help us learn about the environment around us, or about the state of our internal environment. Stimuli from varying sources, and of different types, are received and changed into the electrochemical signals of the nervous system. This occurs when a stimulus changes the cell membrane potential of a sensory neuron. The stimulus causes the sensory cell to produce an action potential that is relayed into the central nervous system (CNS), where it is integrated with other sensory information—or sometimes higher cognitive functions—to become a conscious perception of that stimulus. The central integration may then lead to a motor response. Describing sensory function with the term sensation or perception is a deliberate distinction. Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived. Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes. Transmembrane receptors are activated by chemicals called ligands. For example, a molecule in food can serve as a ligand for taste receptors. Other transmembrane proteins, which are not accurately called receptors, are sensitive to mechanical or thermal changes. Physical changes in these proteins increase ion flow across the membrane, and can generate an action potential or a graded potential in the sensory neurons.

A store that sells husbands has just opened in Ottawa where a woman may go to choose a husband from many men. The store is comprised of 6 floors and the men increase in positive attributes(,)as the shopper goes up the flights. There is, however, a catch . As you open the door to any floor you may choose a man from that floor, but if you go up a floor, you cannot go back down except to exit the building. So a woman goes to the shopping center to find a husband. On the first floor the sign on the door reads: Floor 1--These men have jobs. The woman reads the sign and says to herself, "Well, that's better than my last boyfriend, but I wonder what's further up?" So up she goes. The second floor sign reads: Floor 2--These men have jobs and love kids. The woman remarks to herself, "That's great, but I wonder what's further up?" And up she goes again. The third floor sign reads: Floor 3--These men have jobs, love kids and are extremely good-looking. "Hmm, better." The fourth floor sign reads: Floor 4--These men have jobs, love kids, are extremely good-looking and help with the housework. "Wow!" exclaims the woman, "Very tempting. But, there must be more, further up!" And again she heads up another flight. The fifth floor sign reads: Floor 5--These men have jobs, love kids, are extremely good-looking, help with the housework and have a strong romantic character. "Oh, mercy me! But just think...what must be awaiting me further on?" So up to the sixth floor she goes. The sixth floor sign reads: Floor 6 -You are visitor 3, 456, 789,012 to this floor. There are no men on this floor. Thank you for shopping Husband Mart and have a nice day. Women tend to go up the floor until they reach the top floor because _ . A. they think the husbands downstairs are not suitable B. they are sure that the best husbands are on the top floor C. they know the catch very well D. they think even better husbands may be upstairs
