"data": "Lecture: Offspring genotypes: homozygous or heterozygous?\nHow do you determine whether an organism is homozygous or heterozygous for a gene? Look at the alleles in the organism's genotype for that gene.\nAn organism with two identical alleles for a gene is homozygous for that gene.\nIf both alleles are dominant, the organism is homozygous dominant for the gene.\nIf both alleles are recessive, the organism is homozygous recessive for the gene.\nAn organism with two different alleles for a gene is heterozygous for that gene.\nIn a Punnett square, each box represents a different outcome, or result. Each of the four outcomes is equally likely to happen. Each box represents one way the parents' alleles can combine to form an offspring's genotype. \nBecause there are four boxes in the Punnett square, there are four possible outcomes.\nAn event is a set of one or more outcomes. The probability of an event is a measure of how likely the event is to happen. This probability is a number between 0 and 1, and it can be written as a fraction:\nprobability of an event = number of ways the event can happen / number of equally likely outcomes\nYou can use a Punnett square to calculate the probability that a cross will produce certain offspring. For example, the Punnett square below has two boxes with the genotype Ff. It has one box with the genotype FF and one box with the genotype ff. This means there are two ways the parents' alleles can combine to form Ff. There is one way they can combine to form FF and one way they can combine to form ff.\n | F | f\nF | FF | Ff\nf | Ff | ff\nConsider an event in which this cross produces an offspring with the genotype ff. The probability of this event is given by the following fraction:\nnumber of ways the event can happen / number of equally likely outcomes = number of boxes with the genotype ff / total number of boxes = 1 / 4\nQuestion: What is the probability that a goat produced by this cross will be homozygous dominant for the myotonia congenita gene?\nHint: This passage describes the myotonia congenita trait in goats:\nMyotonia congenita is a condition that causes temporary muscle stiffness. When goats with myotonia congenita attempt to run from a resting position, their leg muscles often stiffen, causing them to fall over. Because of this behavior, these goats are referred to as fainting goats. Myotonia congenita is also found in other mammals, including horses, cats, and humans.\nIn a group of goats, some individuals have myotonia congenita and others do not. In this group, the gene for the myotonia congenita trait has two alleles. The allele for having myotonia congenita (M) is dominant over the allele for not having myotonia congenita (m).\nThis Punnett square shows a cross between two goats.\nChoices:\nA. 1/4\nB. 0/4\nC. 4/4\nD. 2/4\nE. 3/4\nAnswer with the letter.",

"data": "Lecture: Offspring phenotypes: dominant or recessive?\nHow do you determine an organism's phenotype for a trait? Look at the combination of alleles in the organism's genotype for the gene that affects that trait. Some alleles have types called dominant and recessive. These two types can cause different versions of the trait to appear as the organism's phenotype.\nIf an organism's genotype has at least one dominant allele for a gene, the organism's phenotype will be the dominant allele's version of the gene's trait.\nIf an organism's genotype has only recessive alleles for a gene, the organism's phenotype will be the recessive allele's version of the gene's trait.\nIn a Punnett square, each box represents a different outcome, or result. Each of the four outcomes is equally likely to happen. Each box represents one way the parents' alleles can combine to form an offspring's genotype. Because there are four boxes in the Punnett square, there are four possible outcomes.\nAn event is a set of one or more outcomes. The probability of an event is a measure of how likely the event is to happen. This probability is a number between 0 and 1, and it can be written as a fraction:\nprobability of an event = number of ways the event can happen / number of equally likely outcomes\nYou can use a Punnett square to calculate the probability that a cross will produce certain offspring. For example, the Punnett square below has two boxes with the genotype Ff. It has one box with the genotype FF and one box with the genotype ff. This means there are two ways the parents' alleles can combine to form Ff. There is one way they can combine to form FF and one way they can combine to form ff.\n | F | f\nF | FF | Ff\nf | Ff | ff\nConsider an event in which this cross produces an offspring with the genotype ff. The probability of this event is given by the following fraction:\nnumber of ways the event can happen / number of equally likely outcomes = number of boxes with the genotype ff / total number of boxes = 1 / 4.\nQuestion: What is the probability that a koi fish produced by this cross will have black eyes?\nHint: In a group of koi fish, some individuals have red eyes and others have black eyes. In this group, the gene for the eye color trait has two alleles. The allele for red eyes (E) is dominant over the allele for black eyes (e).\nThis Punnett square shows a cross between two koi fish.\nChoices:\nA. 0/4\nB. 1/4\nC. 4/4\nD. 3/4\nE. 2/4\nAnswer with the letter.",

Substances that are composed of multiple chemical elements bonded together are compounds.\nEvery chemical element is represented by its own atomic symbol. An atomic symbol may consist of one capital letter, or it may consist of a capital letter followed by a lowercase letter. For example, the atomic symbol for the chemical element fluorine is F, and the atomic symbol for the chemical element beryllium is Be.\nScientists use different types of models to represent substances whose atoms are bonded in different ways. One type of model is a ball-and-stick model. The ball-and-stick model below represents the compound pyrite.\nIn a ball-and-stick model, the balls represent atoms, and the sticks represent bonds. Notice that the balls in the model above are not all the same color. Each color represents a different chemical element. The legend shows the color and the atomic symbol for each chemical element in the substance.\nQuestion: Complete the statement.\nTungsten carbide is ().\nHint: The model below represents tungsten carbide. Tungsten carbide can be used to make the tips of ballpoint pens.\nChoices:\nA. an elementary substance\nB. a compound\nAnswer with the letter.",

"data": "Lecture: Offspring phenotypes: dominant or recessive?\nHow do you determine an organism's phenotype for a trait? Look at the combination of alleles in the organism's genotype for the gene that affects that trait. Some alleles have types called dominant and recessive. These two types can cause different versions of the trait to appear as the organism's phenotype.\nIf an organism's genotype has at least one dominant allele for a gene, the organism's phenotype will be the dominant allele's version of the gene's trait.\nIf an organism's genotype has only recessive alleles for a gene, the organism's phenotype will be the recessive allele's version of the gene's trait.\nA Punnett square shows what types of offspring a cross can produce. The expected ratio of offspring types compares how often the cross produces each type of offspring, on average. To write this ratio, count the number of boxes in the Punnett square representing each type.\nFor example, consider the Punnett square below.\n | F | f\nF | FF | Ff\nf | Ff | ff\nThere is 1 box with the genotype FF and 2 boxes with the genotype Ff. So, the expected ratio of offspring with the genotype FF to those with Ff is 1:2.\n\nQuestion: What is the expected ratio of offspring with a hairy body to offspring with a hairless body? Choose the most likely ratio.\nHint: In a group of deer mice, some individuals have a hairy body and others have a hairless body. In this group, the gene for the body hair trait has two alleles. The allele for a hairy body (B) is dominant over the allele for a hairless body (b).\nThis Punnett square shows a cross between two deer mice.\nChoices:\nA. 3:1\nB. 4:0\nC. 2:2\nD. 0:4\nE. 1:3\nAnswer with the letter.",

For example, imagine that you want to find out if fertilizer affects the number of tomatoes a tomato plant grows. To answer this question, you decide to set up two equal groups of tomato plants. Then, you add fertilizer to the soil of the plants in one group but not in the other group. Later, you measure the effect of the fertilizer by counting the number of tomatoes on each plant.\nIn this experiment, the amount of fertilizer added to the soil and the number of tomatoes were both variables.\nThe amount of fertilizer added to the soil was an independent variable because it was the variable whose effect you were investigating. This type of variable is called independent because its value does not depend on what happens after the experiment begins. Instead, you decided to give fertilizer to some plants and not to others.\nThe number of tomatoes was a dependent variable because it was the variable you were measuring. This type of variable is called dependent because its value can depend on what happens in the experiment.\nQuestion: Which of the following was a dependent variable in this experiment?\nHint: The passage below describes an experiment. Read the passage and think about the variables that are described.\n\nPam was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled with salt water for eight hours. Pam wondered if steel would rust faster submerged in vinegar instead of salt water.\nTo find out, Pam cut ten squares of steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares into a tub filled with vinegar. Once an hour for eight hours, Pam counted the number of rusted steel squares in each group.\nHint: An independent variable is a variable whose effect you are investigating.

This group shows you what happens when fertilizer is added to soil. Since fertilizer is the variable whose effect you are investigating, this group is an experimental group.\nYou grow another group of pea plants in soil without fertilizer and measure the height of the plants. Since this group shows you what happens when fertilizer is not added to the soil, it is a control group.\nBy comparing the results from the experimental group to the results from the control group, you can conclude whether adding fertilizer to the soil affects pea plant height.\nQuestion: In this experiment, which were part of an experimental group?\nHint: The passage below describes an experiment.\n\nLayla was using steel to make rusted sculptures.

Chemical elements make up all of the substances around you.\nA substance may be composed of one chemical element or multiple chemical elements. Substances that are composed of only one chemical element are elementary substances. Substances that are composed of multiple chemical elements bonded together are compounds.\nEvery chemical element is represented by its own atomic symbol. An atomic symbol may consist of one capital letter, or it may consist of a capital letter followed by a lowercase letter. For example, the atomic symbol for the chemical element fluorine is F, and the atomic symbol for the chemical element beryllium is Be.\nScientists use different types of models to represent substances whose atoms are bonded in different ways. One type of model is a space-filling model. The space-filling model below represents the elementary substance copper.\nIn a space-filling model, the balls represent atoms that are bonded together. The color of a ball represents a specific chemical element. The atomic symbol for that chemical element is shown in the legend.\nQuestion: Complete the statement.\nPalladium is ().\nHint: The model below represents palladium. Palladium is a metal that reacts with the gases produced by car engines to make the gases less harmful.\nChoices:\nA. a compound\nB. an elementary substance\nAnswer with the letter.",

"data": "Lecture: Offspring phenotypes: dominant or recessive?\nHow do you determine an organism's phenotype for a trait? Look at the combination of alleles in the organism's genotype for the gene that affects that trait. Some alleles have types called dominant and recessive. These two types can cause different versions of the trait to appear as the organism's phenotype.\nIf an organism's genotype has at least one dominant allele for a gene, the organism's phenotype will be the dominant allele's version of the gene's trait.\nIf an organism's genotype has only recessive alleles for a gene, the organism's phenotype will be the recessive allele's version of the gene's trait.\nIn a Punnett square, each box represents a different outcome, or result. Each of the four outcomes is equally likely to happen. Each box represents one way the parents' alleles can combine to form an offspring's genotype. Because there are four boxes in the Punnett square, there are four possible outcomes.\nAn event is a set of one or more outcomes. The probability of an event is a measure of how likely the event is to happen. This probability is a number between 0 and 1, and it can be written as a fraction:\nprobability of an event = number of ways the event can happen / number of equally likely outcomes\nYou can use a Punnett square to calculate the probability that a cross will produce certain offspring. For example, the Punnett square below has two boxes with the genotype Ff. It has one box with the genotype FF and one box with the genotype ff. This means there are two ways the parents' alleles can combine to form Ff. There is one way they can combine to form FF and one way they can combine to form ff.\n | F | f\nF | FF | Ff\nf | Ff | ff\nConsider an event in which this cross produces an offspring with the genotype ff. The probability of this event is given by the following fraction:\nnumber of ways the event can happen / number of equally likely outcomes = number of boxes with the genotype ff / total number of boxes = 1 / 4.\nQuestion: What is the probability that a Nile tilapia fish produced by this cross will have a greenish-brown body?\nHint: In a group of Nile tilapia fish, some individuals have a greenish-brown body and others have a pink body. In this group, the gene for the body color trait has two alleles. The allele for a pink body (b) is recessive to the allele for a greenish-brown body (B).\nThis Punnett square shows a cross between two Nile tilapia fish.\nChoices:\nA. 2/4\nB. 3/4\nC. 1/4\nD. 0/4\nE. 4/4\nAnswer with the letter.",
