88) The plasma membrane proteins of a cell can be linked to colored marker molecules. In an experiment, you labeled the membrane proteins of one cell with a red marker and the membrane proteins of a second cell with a blue marker. Using your understanding of the fluid-mosaic model, what might you see happen if you connected the plasma membranes of the two cells so that they form one continuous membrane?

89) A woman suffering from severe dehydration goes into the hospital. The doctor tells the woman that her blood has far too much solute in it and not enough water. Explain how this condition could affect the cells of her body and why.

90) An accident victim lost a lot of blood and was rushed to the emergency room. In the emergency room, the first thing the doctors did was replace lost fluids by giving an IV of pure water. But this caused the patient to die. Propose a reason why the patient died.

91) What are two major differences between active transport and passive transport? Please give a specific example of each that occurs within a eukaryotic cell.

Refer to the figure below, and then answer the question that follows.

92) For this type of transport to take place, which of the following must be true about the interior and exterior environments?

A) The amount of glucose outside the cell must be less than the interior concentration.

B) The glucose concentration must be higher outside the cell than inside the cell.

C) The glucose concentrations on both sides of the cell must be the same.

D) A transport protein is involved, so it doesn’t matter what the concentrations of glucose are on either side of the membrane.

Refer to the figure below, and then answer the question that follows.

93) The type of transport shown is an example of:

A) simple diffusion.

B) active transport.

C) endocytosis.

D) exocytosis.

E) facilitated diffusion.
