11. how does active transport differ from all other forms of transportation? a. it creates an equilibrium shiftb. it maintains homeostasisc. it shifts from high to lowd. it requires energy

Though both active transport and passive transport involve ion movement and use ion channels to move ions across the cell membrane, in or out of the cell.

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

So the answer is C.

a. suckling by young

b. hypothalamus

c. dopamine

d. trh

e. anterior pituitary

f. mammary glands

g. milk production
