Marie and Joan are the same height, but Marie weighs 25 pounds more than Joan. When they go hiking in cold weather, Joan needs two more layers of clothing than Marie to stay warm. Which of the following explains why? Marie has more subcutaneous fat, which is metabolized to provide warmth. Marie has more dermal blood vessels, which constrict to increase blood flow to the core. Marie has more subcutaneous fat, which insulates the body's core. Marie has a thicker epidermal layer, which insulates her body's core more efficiently.
