Question

A population of snowshoe hare rabbits live in a particular region of the arctic tundra that experiences high winds, extremely cold temperatures, and gets very little snow. Their main predator is nocturnal and hunts by sound. Which of the following mutations would best be classified as an adaptation?
A Longer and more vascularized ears
B Being less active in the day and more active at night
C A dense undercoat of fur beneath a longer top coat of fur
D A fur coloration pattern that allows them to visually camouflage with their surroundings

Answer 1

The correct answer for the question that is being presented above is this one: "C A dense undercoat of fur beneath a longer top coat of fur." A dense undercoat of fur would help to insulate the rabbits and prevent them from losing body heat in a cold, windy environment and so could be called an adaptation.
