Question 10

is any process, active or passive, by which a substance moves from one side of a membranetotheothersideofthe membrane.

Answer 10

membrane transport

Question 11

requires no input of cellular energy.

Answer 11

passive transport

Question 12

net movement of molecules from an
area of higher concentration to an area of lower concentration.

Answer 12

diffusion

Question 13

When the molecules are even throughout a space - it is called

Answer 13

equilibrium

Question 14

Factors affecting the rate of diffusion

Answer 14

magnitude of concentration difference across the membrane

Size and shape of particles of solute

temperature

Question 15

Movement of solute from an area of lower concentration to an area of higher concentration

Answer 15

osmosis

Question 16

is the hydrostatic pressure produced by a difference in concentration between solutions on the two sides of a surface

Answer 16

osmotic pressure

Question 17

means the same

Answer 17

iso

Question 18

the concentration of solute (salt) is equal on both sides, the water will move back in forth but it won’t have any result on the overall amount of water on either side.

Answer 18

isotonic solution

Question 19

means less

Answer 19

hypo

Question 20

in this case there are less solute (salt) molecules outside the cell, since salt sucks, water will move into the cell.

Answer 20

hypotonic solution

Question 21

means more

Answer 21

hyper

Question 22

there are more solute (salt) molecules outside the cell, which causes the water to be sucked in that direction

Answer 22

hypertonic solution

Question 24

dialusis

Answer 24

meaning dissolution

Question 25

dia meaning

Answer 25

through

Question 26

lusis meaning

Answer 26

loosening

Question 27

Method of separating particles of different dimensions in a liquid mixture using a thin semi permeable membrane whose pores are too small to allow the passage of large particles such as proteins but large enough to permit the passage of ions

Answer 27

dialysis
