For finches on the Galapagos, a significant change in beak size can be observed across years with plentiful rainfall or intense drought. How can the changes in finch beak size be attributed to evolution?

A) Finches on the island with better-adapted beak sizes have increased survival.
B) Finches on the island are domesticated and are artificially selected for beak size.
C) Finches on the island without well suited beak sizes change their diet to induce and enhance growth of their beaks.
D) Finches on the island reproduce with finches from nearby islands that have larger beaks, resulting in changing beak sizes over time.

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
