True or False: Equilibrium occurs when molecules of one substance are spread evenly throughout another substance.

a)

True

b)

False

5.

True or False: Osmosis is a type of passive transport that occurs when water diffuses through a cell membrane.

b)

True

6.

Diffusion

a)

energy requiring process in which transport proteins bind with particles and move them through a cell membrane

b)
Facilitated diffusion
c)

chemical reactions in which cells release small amounts of energy through the breakdown of food
