Are there multiple choices?
to find the difference you need to determine which one is affected by the other one, and the one affected id the dependent variable and the other one should be the independent
Answer:
To minimize heat loss
Explanation:
Most mammals in colder climates have large body size to minimize heat loss. The smaller the surface area to volume ratio, the less the heat loss to the environment. Hence a large body size helps the organisms to conserve heat. This is known as Bergman rule.
Most mammals in cold climates have large compact bodies and shorter extremities than mammals in hotter climates.
