Question 1

Concentration

Answer 1

The mass of solute in a given volume of solution or mass/volume

Question 2

Diffusion

Answer 2

Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated

Question 3

Equilibrium

Answer 3

When the concentration of a solution is the same throughout the solution

Question 4

Osmosis

Answer 4

Diffusion of water through a selectively permeable membrane

Question 5

Isotonic

Answer 5

When the concentration of two solutions is the same

Question 6

Hypertonic

Answer 6

When comparing two solutions the solution with the greater concentration of solute.

Question 7

Hypotonic

Answer 7

When comparing two solutions the solution with the lesser concentration of solutes

Question 8

Facilitated diffusion

Answer 8

Movement of specific molecules across cell membranes through protein channels

Question 9
