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.
