Osmosis Quiz

What is diffusion?

• The movement of molecules or particles from an area of low concentration to an area of high concentration.

• The movement of molecules or particles from an area of high concentration to an area of equal concentration.

• The movement of molecules or particles from an area of low concentration to an area of equal concentration.

• The movement of molecules or particles from an area of high concentration to an area of low concentration.

Define hypertonic solution.

• A hypertonic solution is a solution that has an equal concentration of solutes compared to another solution.

• A hypertonic solution is a solution that has a higher concentration of solutes compared to another solution.

• A hypertonic solution is a solution that has a lower concentration of solutes compared to another solution.

• A hypertonic solution is a solution that has a higher volume compared to another solution.

Explain hypotonic solution.

• A hypotonic solution has a lower concentration of solutes compared to another solution.

• A hypotonic solution refers to a solution with a higher concentration of solutes compared to another solution.

• A hypotonic solution has the same concentration of solutes compared to another solution.

• A hypotonic solution has a higher concentration of solutes compared to another solution.

What is an isotonic solution?

• A solution that has a lower concentration of solutes than the cell or fluid it is being compared to.

• A solution that does not contain any solutes.

• A solution that has the same concentration of solutes as the cell or fluid it is being compared to.

• A solution that has a higher concentration of solutes than the cell or fluid it is being compared to.
