a)
acid
b)
enzyme
c)

d)
hormone
14.
When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.
a)
Positive Feedback Response
b)
Negative Feedback Loop
15.
When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels.
a)
Positive Feedback Response
b)
Negative Feedback Loop
16.
Rapid growth during puberty causes your body to release more and more growth hormones. As you grow, more and more growth hormones are released until puberty is reached, and then the hormones stop.
a)
Positive Feedback Response
b)
Negative Feedback Loop
17.
If the calcium in your blood decreases below homeostasis levels, a gland in the brain will sense the decrease and send a chemical message to your bones. Your bones will release calcium into the blood, bringing blood calcium levels back up.
a)
Positive Feedback Response
b)
Negative Feedback Loop
18.
As you get dehydrated, your blood becomes thicker and harder to pump. Your kidneys will respond by stopping urine production, sending the water from urine into your bloodstream to thin your blood back to normal level.
a)
Positive Feedback Response
b)
Negative Feedback Loop
19.
