Sample Question
While walking around campus, you notice that hummingbirds often visit red flowers. You wonder why hummingbirds often visit red flowers. You think that perhaps hummingbirds prefer red flowers to flowers of other colors. You conduct an experiment in which you give hummingbirds the choice of visiting a red flower, a white flower, and yellow flower must differ only in color for this experiment to work. In the scenario above, which represents a prediction?

Hummingbirds prefer red flowers to flowers of other colors.

Hummingbirds often visit red flowers.

If hummingbirds prefer red flowers, then they will choose to visit a red flower over a white flower or a yellow flower.

Why do hummingbirds often visit red flowers.

Sample Question
Mrs. Lewis set up a lab for her biology students using a culture of the small crustacean Daphnia, obtained from a pond that was 20°C. The students are to investigate the effect temperature has on Daphnia. The students will observe the crustacean’s heartbeat under the microscope, at the following temperatures: 0°C, 10°C, 20°C, 30°C, and 40°C. They will count the number of heartbeats per second. If the experiment is designed correctly, what will the students choose for the experimental treatment?

Placing 5 identical cultures of Daphnia at 20C

Placing each of 5 identical cultures of Daphnia at a different temperature

Placing 5 cultures, each with a different type of crustacean, at 20C

Placing 5 cultures, each with a different type of crustacean, at a different temperature

Sample Question
What would happen if there was a mutation to Complex I and Complex II of the electron transport chain of cellular respiration so that it could not oxidize NADH?

The proton gradient would not form because the electrons from NADH could not be obtained. No ATP synthesis would occur.

The proton gradient would be created more rapidly since NADH would donate its electrons more readily. ATP synthesis would increase.

The electrons would still pass from Complex III and Complex IV to create a smaller proton gradient. Not as much ATP could be made.

The protons from the matrix would have to diffuse through the membrane to maintain the proton gradient needed for ATP synthase.

Electrons from the proton gradient would be donated to Complex I so that it could function normally.
