Answer the following question given this paragraph: When an action and reaction occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum . Q: When an action and reaction occur, what is transferred from one object to the other, yet in combination it remains the same? Choices: - matter - force - energy - momentum A:
momentum
Answer the following question given this paragraph: A magnet is an object that attracts certain materials such as iron. You're probably familiar with common bar magnets, like the one shown in the Figure below . Like all magnets, this bar magnet has north and south magnetic poles . The red end of the magnet is the north pole and the blue end is the south pole. The poles are regions where the magnet is strongest. The poles are called north and south because they always line up with Earth's north-south axis if the magnet is allowed to move freely. (Earth's axis is the imaginary line around which the planet rotates. ). Q: What are the earth's two poles called? Choices: - southwest and south - east and west - west and south - north and south A:
north and south
Q: Answer the following question given this paragraph: Fiber is a complex carbohydrate that consists mainly of cellulose and comes only from plants. High-fiber foods include whole grains and legumes such as beans. Fiber can't be broken down by the digestive system, but it plays important roles in the body. It helps keep sugar and lipids at normal levels in the blood. It also helps keep food waste moist so it can pass easily out of the body. Q: What does fiber help keep at normal levels in the body? Choices: - salt and cholesterol - bloodpressure - hydration - sugar and lipids A:
A: sugar and lipids
Question: Answer the following question given this paragraph: (A) A wave consists of alternation crests and troughs. The wavelength () is defined as the distance between any two consecutive identical points on the waveform. The amplitude is the height of the wave. (B) A wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain amount of time. A wave with a longer wavelength (bottom) has a lower frequency. Q: What is the term for the height of the wave? Choices: - magnitude - frequency - vibration - amplitude A:
Answer: amplitude

Answer the following question given this paragraph: Linked Genes Violate the Law of Independent Assortment Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other. Genes that are located on separate nonhomologous chromosomes will always sort independently. However, each chromosome contains hundreds or thousands of genes, organized linearly on chromosomes like beads on a string. The segregation of alleles into gametes can be influenced by linkage, in which genes that are located physically close to each other on the same chromosome are more likely to be inherited as a pair. However, because of the process of recombination, or "crossover," it is possible for two genes on the same chromosome to behave independently, or as if they are not linked. To understand this, let's consider the biological basis of gene linkage and recombination. Homologous chromosomes possess the same genes in the same linear order. The alleles may differ on homologous chromosome pairs, but the genes to which they correspond do not. In preparation for the first division of meiosis, homologous chromosomes replicate and synapse. Like genes on the homologs align with each other. At this stage, segments of homologous chromosomes exchange linear segments of genetic material (Figure 12.18). This process is called recombination, or crossover, and it is a common genetic process. Because the genes are aligned during recombination, the gene order is not altered. Instead, the result of recombination is that maternal and paternal alleles are combined onto the same chromosome. Across a given chromosome, several recombination events may occur, causing extensive shuffling of alleles. Q: How do genes located on separate nonhomologous chromosomes sort? Choices: - mechanically - intradependently - typically - independently A:
**Answer**
independently
