Answer the following question given this paragraph: A food chain represents a single pathway by which energy and matter flow through an ecosystem. An example is shown in Figure below . Food chains are generally simpler than what really happens in nature. Most organisms consumeand are consumed bymore than one species. Q: A single, often oversimplified, path through which energy and matter flow through an ecosystem is also known as what? Choices: - the chain - fuel chain - life cycle - food chain A:
food chain
Answer the following question given this paragraph: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. The carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form an alcohol. The hydroxyl groups can undergo substitution reactions, resulting in derivatives of the original compound. One such derivative is Sucralose, an artificial sweetener that is six times sweeter than sucrose; it is made by replacing two of the hydroxyl groups on sucrose with chlorine. Carbohydrates can also eliminate hydroxyl groups, producing alkenes. Q: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. the carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form this? Choices: - glucose - sucrose - caffeine - alcohol A:
alcohol
Q: Answer the following question given this paragraph: The human skeleton includes bones and cartilage. Q: What includes the bones and cartilage? Choices: - skull - lungs - fossil - skeleton A:
A: skeleton
Question: Answer the following question given this paragraph: Genes that are located on the same chromosome are called linked genes . Alleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-over occurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over. At the following link, you can watch an animation showing how genes on the same chromosome may be separated by crossing-over: http://www. biostudio. com/d_%20Meiotic%20Recombination%20Between%20Linked%20Genes. htm . Q: Linked genes are located on the same what? Choices: - genome - nucleolus - bacterium - chromosome A:
Answer: chromosome

Answer the following question given this paragraph: where k is a constant equal to Electric Potential. Q: What radiation, generally produced by thermal motion and the vibration and rotation of atoms and molecules, literally means "below red"? Choices: - microscopic - ultraviolet - gamma radiation - infrared A:
**Answer**
infrared

Answer the following question given this paragraph: Solids that change to gases generally first pass through the liquid state. However, sometimes solids change directly to gases and skip the liquid state. The reverse can also occur. Sometimes gases change directly to solids. Q: When solids change to gasses, they generally pass through what other state? Choices: - chemical - frozen - carbon - liquid A:
(Answer)
liquid
