AP Biology Lab 11-12 Take-Home Exam

AP Exam time is fast approaching! Try these teacher-tested, take-home tests to let your students determine their readiness for the upcoming exams. These are great for review after each lab or as a group as a final review.

Lab 11 (Behavior)

  1. Define and give an example of  taxis.

  2. Define and give an example of kinesis.

  3. Define and give an example of phototaxis.

  4. In this lab, pill bugs (isopods/ terrestrial crustaceans/arthropods) were used. After the pill bugs have been in the choice chamber for 10 minutes, you might observe one of these situations:

    Situation A: Wet: 5 pill bugs Dry: 5 pill bugs
    Situation B: Wet: 7 pill bugs Dry: 3 pill bugs
    Situation C: Wet: 2 pill bugs Dry: 8 pill bugs

    Pill bugs are crustaceans, and they respire through gills. Because of this characteristic, which situation would you predict to occur: A, B, or C?

    Explain your answer.

  5. This brings us to an important consideration: The pill bug exercise is not a controlled experiment. Without a control, it is very risky to state a conclusion. Design a controlled experiment. Be sure to include your Hypothesis, Null Hypothesis, IV, DV, and predictions of results.

  6. Courtship Behavior in Fruit Flies: Courtship between male and female animals usually is a ritual with specific behaviors. Is there an advantage to this for the species and/or individual?  Explain your answer.

Lab 12 (DO and PP)

  1. Create a graph showing the relationship between temperature and the percent saturation of dissolved oxygen.

  2. Create a graph showing the relationship between the amount of light received and the amount of productivity.

  3. Create a graph that shows the relationship between the amount of oxygen consumed by photosynthetic organisms and the amount of carbon fixed.

  4. Why is net productivity lower than gross productivity?

  5. What process occurs at night in water systems that lowers the amount of oxygen?
