Biology Released Form I Test Review

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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.

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

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)

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

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

19. B Win Win for both = mutualism

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

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

22. C No ribosomes = no proteins PEAR

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

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

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

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

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

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.

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

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

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

32. A Not an instinctive behavior

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

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

35. D Everything was originally classified under plants and animals

36. C B-cells produce antibodes

37. B Leaves are where photosynthesis occurs

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

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!

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

41. D Chloroplasts are where photosynthesis occurs

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

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

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

45. D Know the equations!!!!!

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

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

48. D Evolution by natural selection!

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

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

51. D See board

52. C Only answer that makes sense

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

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

55. C Guard cells open and close the stoma.

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

57. A Old people can’t eat burgers

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

59. B Win win - mutualism

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.
