1. Biology Released Form I Test Review

2. 1. B Iodine turns from brown to blue or black in the presence of starch

3. 2. D Salt sucks water towards it. The water leaves the gums moving from a high concentration to a low concentration

4. 3. B Proteins are synthesized at the ribsomes which are the little dots. PEAR!

5. 4. D Anaerobic means no oxygen is used. Bacteria and yeast do this.

6. 5. A The plant cells that divide the fastest are root tip cells

7. 6. D The similarities in bone structure in animals indicate a common ancestor from which all mammals diverged

8. 7. C Change the DNA into mRNA first and then translate

9. 8. C O blood is ii. Only parents who are heterozygous for Type A and heterozygous for Type B each have a little i to contribute to their child.

10. 9. B The bands on the DNA fingerprint are an example of gel electrophoresis. Gel electrophoresis separates DNA fragments by size. The larger bands are at the top of the gel.

11. 10. A Independent assortment is the only answer associated with sexual reproduction

12. 11. A Parent one is pp and parent two is PP. All children will be Pp so none will have PKU.

13. 12. C Skin cancer is caused by excessive exposure to sun which gives off ultraviolet radiation

14. 13. D Malaria reproduces inside human red blood cells. It is transmitted from human to human by mosquitoes.

15. 14. A Gymnosperms are plants with cones. Angiosperms are plants with flowers (you have to give Angie flowers before you date her). They both have seeds and vascular tissues.

16. 15. C Pavlov’s experiment is an example of conditioning.

17. 16. C Xylem transports water while phloem transports sugars. They are both examples of vascular tissues. WXYZYlem (the W is for water) Phloem transports Food! (both start with an F sound)

18. 17. B Leaves are where photosynthesis happens and in limited sunlight you need lots of surface area so large leaves

19. 18. D Frogs eat crickets only – they will be the most affected.

20. 19. B Win Win for both = mutualism

21. 20. A Ozone is destroyed by CFC’s (chlorofluorocarbons) Do not get it confused with global warming which is Carbon Dioxide released by burning fossil fuels

22. 21. C You must know that RNA and DNA are nucleic acids

23. 22. C No ribosomes = no proteins PEAR

24. 23. D Water moving is osmosis. When you see osmosis look for answers with water in them!

25. 24. A Structure X is the substrate Structure Y is the enzyme (it doesn’t change) Structure Z is the product

26. 25. B Species X produces products for aerobic respiration Species Y produces product of anaerobic respiration (fermentation)

27. 26. B Hitchhikers thumb is dominant. Woman does not have it so she is hh! Man is Hh. Probability is 50/50

28. 27. A The advantage of sexual reproduction is genetic variation in offspring!!!!

29. 28. A Change first A of DNA to a C. Then transcribed into RNA. Does the amino acid change? If so then one amino acid changes.

30. 29. C Genetically engineered bacteria is currently used to make human insulin and human growth hormone.

31. 30. B First organisms where prokaryotic and anaerobic because there was no oxygen on early earth.

32. 31. D Indivudal 6 is male and has the disorder. He has an X and a Y.

33. 32. A Not an instinctive behavior

34. 33. D If you absorb through your skin you need a lot of surface area in order to do that.

35. 34. B Mammals have internal fertilization and development (happens inside the body)

36. 35. D Everything was originally classified under plants and animals

37. 36. C B-cells produce antibodes

38. 37. B Leaves are where photosynthesis occurs

39. 38. A More carnivores equals less herbivores because they eat them. Thus the producers are not being eaten.

40. 39. D Acids have low pHs. pH of 2 is the strongest acid and all the plants die. pH of 7 is neutral like water. Therefore high acidity is harmful. A low pH = high acidity!

41. 40. C Only graph C show a population reaching carrying capacity (S-curve)

42. 41. D Chloroplasts are where photosynthesis occurs

43. 42. A The reaction rate will increase or speed up! That is what enzymes do!

44. 43. B Homeostasis is the internal balance or equilibrium in your body

45. 44. C All building blocks of nucleic acids (you must know this!)

46. 45. D Know the equations!!!!!

47. 46. C A 50/50 results in offspring means an Aa and aa cross.

48. 47. A A few survive that are resistant so eventually the population will be resistant to the pesticide

49. 48. D Evolution by natural selection!

50. 49. D Soil pH is changing the colors of the flowers and that is an environmental factor.

51. 50. B Clone is a copy. The copy has 12 chromosomes so the plant cell was also 12 chrosomes

52. 51. D See board

53. 52. C Only answer that makes sense

54. 53. A All of the rest involve some part of sexual reproduction. Only A has one parent.

55. 54. C A karyotype is a picture of a person’s chromosomes.

56. 55. C Guard cells open and close the stoma.

57. 56. C Plants, some protists, and some bacteria can do photosynthesis

58. 57. A Old people can’t eat burgers

59. 58. B Only one that is correct. J-curve

60. 59. B Win win - mutualism

61. 60. B Hate this question. Decomposers release carbon dioxide into the atmosphere so if you remove them the amount of carbon dioxide in the atmosphere would decrese.
