what can cause an animal cell in a hypertonic solution to shrink?

• diffusion

• osmotic pressure

• global warming

• hypertonic pressure

What is the force that produces the net movement of water out or into a cell?

• diffusion

• facilitated diffusion

• newton's 2nd law

• osmotic pressure

Cells are almost always hypertonic to fresh water-

• true

• false

Equilibrium is reached when the concentration of the substance on both sides of the cell membrane are the same -

• true

• false

diffusion is the process by which molecules move from an area of lower concentration to higher concentration.

• true

• false

The cell uses energy during diffusion.

• true

• false

What happens in facilitated diffusion

• molecules fuse together

• molecules are destroyed

• molecules that cannot directly diffuse across the membrane pass through special protein channels

• all molecules pass through special protein channels

Facilitated diffusion uses the cell's energy.

• true

• false

What is the inside of a cell's lipid bilayer?

• hydrophobic

• hydrophilic

• hydrochloric
