  2. Which of the following would happen if the active site changed shape? X The protein (enzyme) will work faster The protein (enzyme) will work slower or not at all. The nucleic acid will work faster The nucleic acid will work slower or not at all

  3. A scientist testing the affects of a chemical on apple yield sprays an orchard with the chemical. A second orchard does not receive the chemical. In the fall, the number of apples harvested from each forest is counted. Which of the following is the independent variable in the experiment? The first orchard The second orchard The number of apples The chemical

  4. The orchard sprayed with the chemical yields an average of 60 apples per tree, the other orchard yields an average of 40 apples per tree. Based on the data, the scientist would: a. report his data b. test the chemical on other plants c. determine that the chemical increases apple yield d. determine that the results were inconclusive

  5. The mechanism by which evolution occurs is called: Natural Selection

  6. All living things must: • Move • Have two parents • Eat food • Maintain homeostasis

  7. Which of the following organelles contain the information that passes from parent to offspring? Structure 3 Structure 1 Structure 7 Structure 5

  8. If a theory is challenged by new evidence, which of the following could occur? The theory could be altered The theory is accepted, not the evidence The evidence is wrong A vote is taken on whether to accept the new evidence

  9. Which species evolved first? ferns

  10. Which of the following organelles converts sugar into energy? Structure 3 Structure 6 Structure 7 Structure 5

  11. What is the function of structure 11? Maintains homeostasis

  12. Which of the following is not necessarily a distinct property of living things? a. homeostasis b. complexity c. metabolism d. reproduction

  13. All organisms are composed of a. diatoms. b. cells. c. cellulose. d. None of the above

  14. A scientific theory a. is absolutely certain. b. is unchangeable. c. may be revised as new evidence is presented. d. is a controlled experiment.

  15. Which of the following could be found in BOTH the nucleus and the cytoplasm a. nucleolus b. ribosomes c. RNA d. both RNA & ribosomes

  16. Lipid molecules are found in the cell membrane. True or False? True

  17. Lysosomes carry on cellular respiration. True or false? False

  18. Which of the following is part of the cell theory? a. All living things are made of one cell. b. Cells are the basic units of structure and function in organisms. c. Most cells arise from existing cells. d. Cells are nonliving units that make up organisms.

  19. Chamber A contains 40% helium and Chamber B contains 20% helium. Chambers are connected by a tube the molecules are free to cross. Which of the following will occur? A. some helium will move from chamber A to chamber B B. some helium will move from chamber B to chamber A C. helium will remain concentrated in chamber A D. all of the helium will move into chamber B

  20. An animal cell placed in a hypotonic solution will: A. die B. take on water C. lose water D. divide

  21. The picture depicts what stage of meiosis? a. prophase 1 b. anaphase 1 c. metaphase 1 d. metaphase 2

  22. A cell with a diploid number of 24 undergoes meiosis, how many chromosomes are in each daughter cell? a. 6 b. 12 c. 24 d. 48

  23. 6 steps : the cell cycle :: a. 6 steps : prophase b. 3 steps : meiosis c. 9 steps : cytokinesis d. 4 steps : mitosis

  24. cell growth : G1 :: a. mitosis : cytokinesis b. DNA copying : synthesis phase c. mitochondria replication : synthesis phase d. mitosis : meiosis

  25. Which of the following does not provide new genetic combinations? a. random fertilization b. independent assortment c. cytokinesis d. crossing-over

  26. What happens to cells that enter the G0 phase? • They grow for a longer period of time than other cells • They cease to divide anymore • They skip interphase • They die immediately

  27. What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype? a. 0.25 b. 0.66 c. 0.5 d. 1.0

  28. The passing of traits from parents to offspring is called a. genetics. b. development. c. heredity. d. maturation.

  29. The law of segregation explains that a. alleles of a gene separate from each other during meiosis. b. different alleles of a gene can never be found in the same organism. c. each gene of an organism ends up in a different gamete. d. each gene is found on a different molecule of DNA.

  30. Refer to the illustration below. The genotype represented by box 2 is a. GgIi. b. GI. c. GGIi. d. Gi.

  31. Refer to the illustration below. The box labeled “X” represents the phenotype a. Wrinkled, green seeds b. Wrinkled, yellow seeds c. Round, green seeds d. Round, yellow seeds

  32. The two major ideas that Darwin presented in The Origin of Species were that evolution occurred and that natural selection was its mechanism.True or False? True

  33. Homologous structures are similar because they originated in a shared • Ancestry • Environment • Time period • Island

  34. What is an example of coevolution? Endosymbiotic Theory

  35. Which of the following environmental factors does not affect the rate of photosynthesis? a. oxygen concentration b. light intensity c. carbon dioxide concentration d. temperature

  36. Which of the following is not part of cellular respiration? a. electron transport b. Krebs cycle c. glycolysis d. Calvin cycle

  37. Which of the following is the best explanation for the presence of both chloroplasts and mitochondria in plant cells? a. In the light, plants make their own glucose, but in the dark, photosynthesis stops and mitochondria make glucose. b. If plants cannot produce enough ATP in the process of photosynthesis to meet their energy needs, they can produce it in aerobic respiration. c. Sugars are produced in chloroplasts. These sugars can be stored and used by the mitochondria to produce ATP. d. The leaves and sometimes the stems of plants contain chloroplasts, which produce ATP to meet the energy needs of these plant parts. The roots of plants contain mitochondria, which produce ATP.

  38. Which type(s) of RNA is(are) involved in protein synthesis? a. transfer RNA only b. messenger RNA only c. ribosomal RNA and transfer RNA only d. messenger RNA, ribosomal RNA, and transfer RNA

  39. Which of the following is not part of a molecule of DNA? a. deoxyribose b. ribose c. phosphate d. nitrogen base

  40. During DNA replication, a complementary strand of DNA is made from each original DNA strand. Thus, if a portion of the original strand is CCTAGCT, then the new strand will be a. TTGCATG. b. GGATCGA. c. CCTAGCT. d. AAGTATC.
