Question 1

Define homeostasis

Question 2

List the two types of feedback mechanisms.

Question 3

Which is an example of a negative feedback loop?

cells replicating

sweating

childbirth

blood clotting

Question 4

In negative feedback loops the imbalance

increases

decreases

is corrected back to its normal value

Question 5

When it is cold outside, you start to shiver because your body temperature drops. Shivering increases the body temperature returning it to normal. Shivering is an example of a

negative feedback loop

positive feedback loop

osmosis loop

heat transfer loop

Question 6

Which is an example of a positive feedback loop?

cells replicating

sweating

shivering

blood clotting

Question 7

Put the steps of a negative feedback loop in order

the brain sends a message to an effector (tissue/gland)
tissue or gland responds by releasing a hormone or sweat
a message is sent to the brain
body slowly returns to normal
a change is detected by a receptor

Question 8

Which of the following is the best example of homeostasis in the human body?

The secretions from oil glands in the skin decrease as a person ages.

Opposite muscles are used to bend and extend a person’s arm at the elbow joint.

The villi of the small intestine increases the absorption of nutrients from the small intestine into the blood.

More growth hormone is released from the pituitary gland when the level of growth hormone in the blood falls too low.

Question 9

In which of the following ways does perspiring (sweating) help the body to maintain homeostasis?

by decreasing body temperature

by increasing blood sugar levels

by increasin the amount of fluid in the body

by reducing the amount of carbon dioxide in cells

Question 10

10.

When you excerise, you breathing and heart rate increases because your muscles need more oxygen. Your breathing returns to normal when you stop excerising. Is this an example of homeostasis?

Yes

No
