Asked by Angie

When body temperature rises above the normal range, the brain sends signals to sweat glands, causing heat loss through evaporation.
Which statement best explains this process?
Responses

A. It is a positive feedback mechanism because it amplifies the response raising the temperature to restore balance.
A. It is a positive feedback mechanism because it amplifies the response raising the temperature to restore balance.

B. It is a positive feedback mechanism because it stops the response lowering the temperature to restore balance.
B. It is a positive feedback mechanism because it stops the response lowering the temperature to restore balance.

C. It is a negative feedback mechanism because it stops or inhibits the response lowering the temperature to restore balance.

D. It is a negative feedback mechanism because amplifies the response raising the temperature to restore balance.

E. It is unrelated to feedback mechanisms.

C.

This is a negative‑feedback mechanism: thermoreceptors (sensor) detect elevated body temperature, the hypothalamus (control center) signals sweat glands (effectors), and evaporative cooling (response) lowers temperature back toward the set point, counteracting the original change.
