Active and Passive Transport Review

The movement of molecules from an area of high concentration to an area of low concentration is

• Diffusion

• Passive Transport

• Osmosis

• All of the above

What does "semi-permeable" mean?

• Some molecules can move through the membrane

• Nothing can move through the membrane

• All molecules can move the membrane

What is equilibrium?

• When concentrations cannot be balanced between two substances

• When concentrations are balanced between two substances
