Question

1. thermoregulation is one feedback mechanism that helps the body to maintain homeostasis because__________.a. it helps the body regulate temperature. the brain senses a change in the bodys set point (normal temperature range) and tells the body to respond in ways that move the bodys temperature even farther from homeostasis. (positive feedback)b. it helps the body regulate energy production in the mitochondria by controlling the amounts of inputs and outputs, so the body doesnt run out of energy.c. it helps the body regulate temperature. the brain senses a change in the bodys set point (normal temperature range) and tells the body to respond in ways that bring the body temperature back towards normal. (negative feedback)d. it tells the body when to eat so we have enough energy throughout the day.

Explanation:

Thermoregulation is a negative feedback mechanism. Negative feedback works to counteract changes and bring the body back to its normal state (set - point). In thermoregulation, when the brain senses a deviation from the normal temperature range (set - point), it triggers responses. For example, if the body is too cold (blood temperature drops), the brain tells the body to respond (like shivering which generates heat). If the body is too hot (blood temperature rises), the brain tells the body to respond (like vasodilation of blood vessels near the skin to lose heat). This is in contrast to positive feedback (like in childbirth or blood clotting) which moves the body further from the set - point. Option A only mentions regulating temperature but doesn't specify the return to normal (which is key for homeostasis). Option B is about positive feedback which is not thermoregulation. Option D is about eating and energy (not thermoregulation).

Answer:

C. It helps the body regulate temperature. The brain senses a change in the body's set point (normal temperature range) and tells the body to respond in ways that bring the body temperature back towards normal. (negative feedback)
