10.
Homeostasis
a)
allows for a wildly fluctuating internal environment
b)
is impossible in vertebrates
c)
is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
d)
is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation
11.
If the environment gets cold, we will often shiver in order to:

keep body temperature the same as the external temperature
b)
decrease body temperature
c)
increase body temperature
d)
regulate blood pressure
12.

To make sure the conditions in the body are always changing

d)

To make sure the conditions in the body remain stable
