Diffusion

Answer 10

Movement of molecules from an area of higher concentration to an area of lower concentration (high->low)

Osmosis

Answer 11

The diffusion of water across a semipermeable membrane from an area of high water concentration -> low water concentration (high->low)

Question 12

Facilitated Diffusion

Answer 12

To protect the cell and regulate what enters and exits

Question 40

Isotonic solution

Answer 40

EQUAL Equal solute (salt) - equal water

Question 41

Hypotonic solution

Answer 41

Inside: higher solute (more salt, less water) Higher water concentration outside Water enters the cell Hypo -> “hippo” -> swells

Question 42

Hypertonic solution

Answer 42

Inside: higher water concentration (more water, less salt) Higher water inside Water diffuses out of the cell Shrinks
