6. 4 Most of the cell membrane is made up of fats that are arranged in a _______ A protein layer B cholesterol layer C lipid bilayer D none of the above

7. 5 Based on the cell structures they possess and the process of osmosis, which of the following is most likely to burst? A An animal cell in distilled water. B A plant cell in distilled water. C An animal cell in saltwater. D A plant cell in saltwater.

8. 6 Name the type of movement this picture represents. Fresh water moves into a single celled organism A active transpot B osmosis C diffusion D facilitated diffusion

9. 7 Which adaptation would help a plant living in a saltwater environment to absorb water from its surroundings? A having extra thick cell walls B having high concentrations of solutes in its roots C having low concentrations of solutes in its roots D living in cold environments

10. 8 What is most likely to happen to a red blood cell when it is placed in distilled water? A The red blood cell will swell as it absorbs water and possibly burst. B The red blood cell will swell as it absorbs solutes and possibly burst. C The red blood cell will shrink as it loses water. D The red blood cell will shrink as it loses solutes. E The red blood cell won’t change size because its cell membrane is not semi-permeable.
