Question

8) When your body temperature rises on a hot day, the neural and hormonal mechanisms activate

sweating. Evaporation of sweat leads to cooling of the body surface. This is an example of
A) positive feedback regulation
B) negative feedback regulation
C) chemical cycling
D) emergent properties

Answer 1

The situation described involves negative feedback regulation, where the body temperature increases and sweating occurs to cool the body surface.

Step-by-step explanation:

The given situation, where the body temperature rises on a hot day and sweating occurs to cool the body surface, is an example of negative feedback regulation. Negative feedback is a regulatory mechanism in which a change in a variable triggers processes that reverse the change, maintaining homeostasis. In this case, the increase in body temperature triggers sweating, which leads to evaporative cooling and brings the temperature back to a stable level.
