Question 1

Osmosis

Answer 1

When water moves through a membrane to a area with more water to less water

Question 2

Isotonic

Answer 2

Equal concentration on either side

Question 3

Hypertonic

Answer 3

Side with higher solute concentration. Cell shrinking

Question 4

Hypotonic

Answer 4

Lower solute concentration. Water rushes in

Question 5

Tonicity

Answer 5

Comparing concentrations of solute on both sides

Question 6

crenation

Answer 6

Cell shrinking

Question 7

Pores

Answer 7

Allows water and polar molecules to pass through membrane

Question 8

Glycosylation

Answer 8

Attachment of carbohydrates to limit protein

Question 9

N-linked

Answer 9

Carbohydrates attach to nitrogen
