Mark the following statements as true or
false. If a statement is false, correct it to
make a true statement.

related at the organ level only.
b. Homeostasis is the condition of having a
dynamic equilibrium of the internal
environment.
c. Positive feedback loops are triggered by
a deviation from a homeostatic set point
and are shut down when conditions return
to the set point.
d. The effects of negative feedback loops
are amplified to create an escalating
response.
e. Cell-cell communication is required to
coordinate the activities of the whole body
