In a mammal,a thermoregulatory response of the hypothalamus to a rise in temperature is
A) increased metabolic heat production.
B) a resetting of the thermostat to a higher setting.
C) sweating or panting.
D) an overall increase in body temperature.
E) the initiation of shivering.

Question

Quizplus · Accepted Answer

Sweating or panting are the primary mechanisms by which the body dissipates excess heat in response to a rise in temperature. This helps to cool the body down and maintain homeostasis. Increased metabolic heat production and shivering are actually responses to a decrease in temperature, not an increase. A resetting of the thermostat to a higher setting would result in an ongoing rise in temperature, which is not desirable, so it is not a valid response.
