Answer 1

In this situation, the best response regarding how thermal homeostasis is maintained when the outside temperature drops from 60º F to 35º F is:

The student begins to shiver as a negative feedback mechanism to increase the core body temperature.

Shivering is a physiological response that helps to generate heat in the body to maintain core temperature when it is cold outside.
