Mammals lose heat from the surface of their skin. Which of these--elephant or mouse--loses heat fastest? Hint: think about their SA/V ratios.
Elephant because it has more volume to heat up
Elephant because it has larger ears to block the sun
Mouse because it has more surface area per volume
mouse because it doesn't have as much heat
