5.
A red blood cell has lost water due to certain changes inside the body. What causes the water to leave the red blood cell?
a)
The fluid outside the cell is more concentrated with water, causing the red blood cell to shrink.

The fluid outside the cell is less concentrated with water, causing the red blood cell to shrink.
d)
The fluid outside the cell is more concentrated with water, causing the red blood cell to swell.

8.
Eggs were soaked in water and corn syrup, weighed the eggs before and after osmosis occurred.
For Cup A that contained water, before osmosis it weighed 5.5 grams. After the movement of water occurred, Cup A then measured to be 6.5 grams.
Cup B was filled with corn syrup and weighed 5.5 grams before osmosis occurred. After osmosis occurred, it weighed 3.3 grams.
What is the independent variable?

9.
The protein moves small molecules and ions across the cell membrane.
For example, ions are moves from the side where there are few ions to the side where there are more ions.
Which best describes this process of moving ions against a concentration difference?

Salt will move from the bag into the 30% salt solution.
b)
Salt will move from the 30% salt solution into the bag.
c)
Water will move from the 30% salt solution into the bag.
d)
Water will move from the bag into the 30% salt solution.
11.

passive transport by diffusion
b)
active transport using ATP and carrier proteins
c)
passive transport by osmosis
d)
phagocytosis
12.
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?

The swollen gums have absorbed the saltwater solution.
b)
The saltwater solution lowers the temperature of the water in the gums.
c)
The salt in the solution has moved against the concentration gradient.
d)
The water in the gums has moved out due to the high concentration of salt in the solution.
13.
