Q

What is the difference between nerves and hormones?

A

Hormones act slower than nerves and affect a region in the body. Nerves are quick and target specific areas.

Q

What is the difference between an endotherm and an ectotherm?

A

Endotherms produce their own body heat. The body heat of ectotherms is based on their environment.

Q

What is torpor?

A

The state in which physical activity is low and metabolic rate decreases. Hibernation is an example of a long term state or torpor.

Q

Give an example of negative feedback

A

When you are thirsty, your control center is stimulated, tells you to drink water, and it’s negative because once you drink water you are not thirsty anymore so it stops.
