Osmosis and Tonicity

Which of the following is an example of osmosis?

• Water moving from a less concentrated solution to a more concentrated solution through a cell membrane

• Water moving from a less concentrated solution to a more concentrated solution through diffusion

• Water moving from a less concentrated solution to a more concentrated solution through active transport

• Water moving from a more concentrated solution to a less concentrated solution through a cell membrane

What happens to a red blood cell when placed in a hypertonic solution?

• It expands and undergoes lysis.

• It remains unchanged.

• It shrinks and undergoes crenation.

• It becomes more rigid and loses its flexibility.
