Charles Darwin observed the Galapagos finches during his time on a chain of islands that were isolated from other major land forms. Darwin noted that after a long period of drought, large seeds and hard nuts were the primary source of food remaining for the small birds.
Which statements are conclusions that can be made about the survival of these finch populations? Select TWO correct answers.
A. Populations of finch 1 have the best chance of survival because their beaks are large and strong enough to crack large seed and hard nuts.
B. Populations of finch 2 have the best chance of survival because their beaks are small enough to carry large seeds and hard nuts to their nest.
C. Populations of finch 3 have the best chance of survival because their beaks are small and can crack open hard nuts.
D. Populations of finch 4 have the best chance of survival because their beaks are narrow which can carry more seeds to their nests.
E. Populations of finch 3 have the least chance of survival because their beaks are small and cannot crack open hard nuts.

The mice in a certain population have fur colors that range from very light to very dark. About 6,000 years ago, the population migrated from an area with dark volcanic soil to a nearby area with light-colored sand. In both areas, the mice's main predators were hawks that hunt by spying prey from above. The diagram shows how the shades of mouse fur in the population appear against both the dark soil in their old habitat and the light-colored soil in their new habitat.
Answer ALL QUESTIONS below.
1. Which shade of mouse fur was LIKELY most frequent when the population lived in the dark-soil habitat?
2. After living in the light-colored-sand habitat for 6,000 years, how was the frequency of fur shades in the mouse population MOST LIKELY changed? AND WHY?
1. The dark-colored fur
2. After living in the light-colored-sand habitat, the light-colored fur mice were more likely to survive and reproduce because they could hide from the hawk predators.
