Sweating and shivering are necessary adaptations because

A) all parts of the body must remain at normal body temperature to maintain life.
B) the health of vital organs requires a near-normal temperature,and metabolic rate fluctuates with changes in the environment.
C) to ensure that total metabolic rate remains constant,the body generates or releases heat as needed.
D) proteins rapidly denature when tissue temperature drops below 98.5 ^$\circ$ F.
