Question

question 2 of 10
what is the best example of how the nervous system maintains homeostasis?

a. it makes muscles move.

b. it receives physical sensations.

c. it regulates breathing and heartbeats.

d. it allows the eyes and brain to communicate.

Explanation:

Homeostasis is the maintenance of stable internal conditions. The nervous system regulates vital functions like breathing and heartbeats (involuntary actions) to keep internal conditions stable. Option A is about movement (not direct homeostasis), B is about sensation (not regulation), D is about sensory communication (not homeostasis regulation). So C is correct as regulating breathing/heartbeats maintains internal balance.

Answer:

C. It regulates breathing and heartbeats.
