1. Where would a nonpregnant patient with normal anatomy most commonly have pain in acute appendicitis?

2. Which of the following is not a type of connective tissue?

3. A student's science fair project involves studying the effects of fertilizer on grass height. After four weeks of measuring height weekly, the student was not able to tell any difference between two pots of grass he had fertilized and watered weekly. How could this experiment be improved?

4. Which of the following is not provided as a result of the valid research and observations recorded by scientists?

5. What is the proper order of the divisions of the small intestine as food passes through the gastrointestinal tract?

6. Which statement correctly pairs the phase of reproduction with the location where that phase occurs?

7. Which structure of the nervous system carries action potential in the direction of a synapse?

8. Which of the following statements best defines an organelle?

9. In the human skeleton, which of the following lists some of the vertebrae in descending order?

10. A biology student is studying the effects of acid rain on tomato plants. He plants four tomato plants in identical pots, using the same type of soil to fill each pot. He places the pots together in the same location. They receive the same amount of sunlight and water each day. The only difference is the pH of the water used to water the plants. The first plant receives water with a neutral pH of 7, which will allow the student to better determine the effects of giving plants water that is more acidic. The second plant receives water with a pH of 5. The third receives water with a pH of 3. The fourth receives water with a pH of 1. Which of the following is a serious flaw in the design of this experiment?

11. The triceps reflex:

15. Which statement correctly matches the valve with its function in the heart?

16. Which of the following describes an experiment?

17. What laboratory practice can increase the accuracy of a measurement?

18. When animals eat, insulin is released from the pancreas, stimulating glucose uptake by the liver. When glucose levels drop, the pancreas reduces insulin release. This is an example of which mechanism for maintaining homeostasis?

19. Homeostasis is defined as:

20. Which of the following statements is FALSE?

21. Which of the following describes enlargement of an organ or tissue?

22. What is the first line of defense against invading bacteria?
