Based on what you've learned, briefly explain the evolutionary significance of the fact that parents pass on their chromosomes to their children. What happens when there is an error in the mechanisms by which chromosomes are passed down? What are some genetic disorders that can arise from mutations that are either inherited or acquired? A sample answer might look like this: Parents pass on their chromosomes to their children because the DNA, packaged in the chromosomes, provides the instructions for all cells in the body to function. If there is an error in the mechanisms by which chromosomes are passed down, the chromosomes may not be passed down properly. This could lead to genetic disorders. There are many examples of genetic disorders that range from very minor to very severe. A frameshift mutation causes Tay-Sachs disease, an autosomal recessive disorder that is typically fatal. Frameshift mutations, in which the DNA or RNA sequence's reading frame is shifted by the addition or deletion of nucleotides, can have catastrophic consequences.

What is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.

If you were given a map of the sensory cortex in the postcentral gyrus of the cerebrum, do you think the map would have more “space” devoted to the regions of the body that have the highest density of sensory receptors, or the regions of the body that have the lowest density of sensory receptors? explain.
