1. Using the graph, describe the events that occur in the body during the first year of HIV infection.

2. Describe what happens between the first year and the tenth year of infection.

3. Explain why the concentration of antibodies begins to decrease after nine years of
infection.

4. At what point on the graph does an infected person have AIDS?

5. Why does the number of HIV particles begin to level off after nine years?

6. How do you think the high rates of HIV transmission in humans might be related to the length of time it takes for the virus to develop into AIDS?

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
