C. / excess carbon monoxide could be removed.
D. / lightning discharge through the gases could be simulated.

A scientist conducted an experiment to determine the effect of environment on the color of fur of a Himalayan rabbit. The Himalayan rabbit typically has a white coat except for its colder nose, feet, tail, and ears, which are black. The scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on one rabbit (A).

4.In Figure 1-1, which rabbit is the control?

A. / B
B. / A
C. / Not enough information

5.In Figure 1-1, what is the variable in this experiment?

A. / size of trimmed area / C. / colorof fur
B. / species of rabbit / D. / ice

6.Based on your observations of Figure 1-1, conclude what effect temperature has on Himalayan rabbits.

A. / contact of skin to cold surface will produce black fur
B. / temperature has no effect
C. / fur turns white when exposed to air
D. / not enough study conduct to come up with a good answer

7.

8.

The diagram above shows two human blood vessels, 1 and 2, connected by a capillary bed, 3. Blood pressure is higher in vessel 2 than in vessel 1. The arrows indicate the direction of diffusion of O2 and CO2. In which location, X or Y, will the concentration of O2 in the blood be higher?

A. / Not enough information / C. / Y

A scientist set up a respiration chamber as shown below. She placed a mouse in flask B. Into flasks A, C, and D, she poured distilled water mixed with the acid-base indicator phenolphthalein. In the presence of CO2, phenolphthalein turns from pink to clear. She allowed the mouse to stay in the chamber for about an hour.

9.Whish flask will contain a clear liquid after the time is up?

A. / D / C. / C
B. / A / D. / They will all still be pink

10.Refer to the illustration above. Amy wants to test the hypothesis that the rate of photosynthesis is directly related to the light level to which plants are exposed. She has chosen the aquatic plant Elodea as her study organism. In her experimental design, she has four different tanks in which she will place Elodea plants. Each Elodea plant will be placed inside an inverted test tube. She plans to estimate the relative rate of photosynthesis by measuring the amount of oxygen produced by plants placed under different light levels. She plans on comparing the amount of oxygen gas that collects in the top of each of the test tubes. Her experimental set-up looks like this:

Amy plans to place tank #3 next to a window in the classroom. She plans to place tank #2 ten feet away from the window. She plans to place tank #1 twenty feet away from the window. She plans to place tank #4 in the classroom's refrigerator, because it is the only place she can find that is dark.

Which tank will produce more bubbles in the test tubes?

A. / 2 / B. / 3 / C. / 1 / D. / 4

The diagram below shows a portion of a plant’s vascular system.

11.Refer to the illustration above. Which structure allows the cytoplasm of one cell to connect to the cytoplasm of a neighboring cell?

A. / 5 / B. / 4 / C. / 1 / D. / 3

Figure 15-3

12.Vegetation on one island is sparse and sometimes hard to reach. Which is island is it?

A. / Not enough information / C. / Isabella
B. / Hood / D. / Pinta

Figure 3-5

13.How might a large omnivore change the flow of energy in Figure 3-5, Diagram II?

A. / would be added to level 4
B. / would have hard time getting energy due to competition from other organisms
C. / would absorb energy from all levels, thus reducing energy for other organisms
D. / would be added to level 3

14.Would you expect the DNA of crocodilians to be more similar to the DNA of modern birds or the DNA of turtles?

A. / shares no DNA with either / C. / Not enought information
B. / Turtles / D. / Birds
