Question

During a race, the body temperature of a runner increases. The runner responds by perspiring, which lowers body temperature. This process is an example of Question 1 options:

A.Maintenance of homeostasis by positive feedback
B.Maintenance of homeostasis by negative feedback
C.A chemical defense against predators

Answer 1

B. Maintenance of homeostasis by negative feedback

Step-by-step explanation:

A negative feedback loop is one where the body responds by changing the expected outcome.

So as the runner's body temperature increases, they perspire, which LOWERS their body temperature. This means that perspiring is a response that changes the original response, as their body temperature decreases rather than continuing to increase from exertion.
