21
Q

What is a solvent?

A

The substance in which a solute diffuses

22
Q

What is a solute?

A

A substance that dissolves into another

23
Q

What is a solution?

A

A mixture of a solute and a solvent

24
Q

What type of solutions are there?

A

Isotonic
Hypotonic
Hypertonic

25
Q

What is an isotonic solution?

A

A solution where the ratio of solute particles to water particles is the same as the ratio inside a cell

26
Q

What is it called when water particles will move equally in both directions?

A

Dynamic diffusion

27
Q

Which organ is responsible for making sure that blood is an isotonic solution?

A

The kidneys

28
Q

What is maintaining the correct water balance in the body called?

A

Osmoregulation

29
Q

What is a hypotonic solution?

A

A solution where the amount of water particles is greater than the amount of solute particles in relation to the inside of a cell

30
Q

What is an example of a hypotonic solution?

A

Distilled water

31
Q

What is a hypertonic solution?

A

A solution where the number of solute particles is greater than the number of water particles in relation to a cell

32
Q

What is an example of a hypertonic solution?

A

Salty solution

33
Q

In a hypertonic solution, what is the concentration of solute particles in the solution in relation to the cell?

A

High

34
Q

In a hypertonic solution, what is the concentration of solute particles inside a cell?

A

Moderate

35
Q

In a hypertonic solution, what is the water potential of a cell?

A

High

36
Q

In a hypertonic solution, what is the water potential of the solution?

A

Low

37
Q

In a hypertonic solution, what will happen to a cell?

A

The cell will shrivel

38
Q

Why will a cell do this in a hypertonic solution?

A

There is a higher concentration of water inside the cell , so the water particles will move to the lower concentration outside.

39
Q

In a hypotonic solution, what will be the concentration of solutes in the solution in relation to the cell?

A

Low

40
Q

In a hypotonic solution, what will the concentration of solutes be inside the cell?

A

Moderate

41
Q

In a hypotonic solution, what will the water potential of the cell be?

A

Low

42
Q

In a hypotonic solution, what will the water potential of the solution be?

A

High

43
Q

In a hypotonic solution, what will happen to a cell?

A

It will expand/burst

44
Q

Why will this happen to a cell in a hypotonic solution?

A

There is a lower concentration of water inside the cell, so the water particles will move from the higher concentration outside.

45
Q

What is an example of an isotonic solution?

A

Blood
