Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin. Which statement best relates why these animals have so much blubber? Lipids in blubber insulate the animals from cold water. Proteins in blubber help the animals move to stay warm. Carbohydrates in blubber provide all the energy that the animals need to stay warm. Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.
