Quiz 1 - Chapter 2

Question 1

Solution

Answer 1

a homogenous mixture of 2 or more substances; body full of solutions; outside of cells (blood plasma, interstitial fluid); inside of cells (cytoplasm)

Question 2

Solute

Answer 2

substances present in smaller amounts; are the molecules that are dissolved in the solvent

Question 3

Solvent

Answer 3

substance present in largest amount

Question 4

Concentration

Answer 4

relates relative amounts of solutes and solvent

Question 5

Volume

Answer 5

amount of space that matter occupies (1L = 10dl = 1000 ml)

Question 6

Mass

Answer 6

amount of matter (1 kg = 1000 g = 1,000,000 mg)

Question 7

Diffusion

Answer 7

net movement of atoms or molecules from an area of high concentration to low concentrating

Question 8

Osmosis

Answer 8

the diffusion of a solvent across a semi-permeable membrane that prevents movement of certain solutes

Question 9

Osmotic pressure

Answer 9

how strongly a solution will pull water into it by osmosis; the solution with more osmotically active solute particles will have a greater osmotic pressure

Question 10

Hypertonic

Answer 10

the solution outside of the cell has a higher osmolality than the solution inside of the cell

Question 11

Isotonic

Answer 11

osmolality of the solution outside of the cell is equal to the osmolality inside the cell

Question 12

Hypotonic

Answer 12

the solution outside of the cell has a lower osmolality than the solution inside of the cell
