1.        Exam content shall include a comprehensive evaluation of the student.

2.        The exam shall take the full 1 hour and 10 minutes.

3.        Students will not be allowed to bring into the exam any study material for any exam, other than the exam they are currently taking. This means there will be no backpacks allowed in the classroom.

4.        The student will need a pencil, eraser, and calculator to complete the exam. No other materials are necessary, nor allowed.

5.        Any student completing the exam before the end of the exam period shall review their exam answers for correctness and accuracy. No exam may be turned in before the end of the exam period.





1.        What is the difference between inference and observation?

2.        How would one determine whether something was living or nonliving?

3.        What are the fur groups of organic compounds found in living things?

4.        Compare enzyme activity to a lock and key.

5.        How do prokaryotes and eukaryotes differ?

6.        A hypertonic salt solution has a higher concentration of solutes than a blood cell. Explain what happens when a blood cell is placed in a hypertonic salt solution.

7.        Summarize three statements from the cell theory. Explain the significance of the cell theory to biology.

8.        Discuss the relationship between autotrophs and heterotrophs. Do heterotrophs depend on autotrophs for their survival? Explain your answer.

9.        Identify three factors that affect the rate of photosynthesis, and explain the effect of each.

10.     Trace the events that occur in the thylakoid membrane during the light-dependent reactions.

11.     List the main events of glycolysis. How many ATP molecules are produced and consumed by glycolysis? What effect does the presence of oxygen have on the events that follow glycolysis?

12.     Compare lactic acid fermentation with alcoholic fermentation. Where does each process occur? What are the products of each process?

13.     What kinds of problems does growth cause for cells? How does cell division help a cell solve these problems?

14.     List and describe the main events of the cell cycle. Illustrate your description with a diagram of the cell cycle.

15.     Explain why short plants reappeared in Mendelís F2 generation of pea plants.

16.     The stages of meiosis are classified into two divisions: meiosis I and meiosis II. Compare and contrast these two divisions.

17.     Heterozygous male guinea pigs with black, rough hair (BbRr) are crossed with heterozygous female guinea pigs with black, rough hair (BbRr). In guinea pigs, the recessive gene b is for white hair, and the recessive gene r is for smooth hair. What are the genotypes and phenotypes of the offspring resulting from this cross?

18.     Red (R) is incompletely dominant to white (r) in snapdragons. The heterozygous genotype produces a pink snapdragon. If a red snapdragon (RR) is crossed with a white snapdragon (rr), what will be the genotypes and phenotypes of the F1 and the F2 offspring?

19.     Describe the structure of a DNA molecule.

††††††† 20. Contrast the functions of the three main types of RNA.
