1. What is the function of meiosis?

2. Explain how the number of chromosomes per cell is cut in half during meiosis in which the diploid parent cell produces haploid daughter cells.

3. At what phase of meiosis is the number of chromosomes per cell doubled? (Think carefully about this.) What happens after that so that the number of chromosomes per cell does not end up being higher?

4. How many times does the cell divide during meiosis?

5. Why are the cells produced by meiosis considered gametes?

Dr. kaylan is an ecologist who studies bird behavior. she sets up an experiment to test which type of food crows are most likely to eat when given a choice between walnuts, corn, and sunflower seeds. to perform her experiment, dr. kaylan places three food bins in an area frequented by cows. each bin contains one of the three food types. then, she measures how much of each food type is eaten every day for a month and summarizes the results of her experiment in the pie chart below. based on her results, dr. kaylan concludes that crows choose to eat corn more frequently than other food sources because it has a higher nutritional value. what is a reasonable alternate conclusion that can be drawn from dr. kaylan's data
