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.
