65. The discharging of molecules outside the sell membrane is called: F 100

66. exocytosis F 100

67. The process of a cell importing a material that does not have to be recognized is called? F 200

68. Phagocytosis F 200

69. Why is osmoregulation important to a cell? F 300

70. To maintain the water balance in the cell. F 300

71. If something happened to a paramecium that caused its contractile vacuole to stop contracting, one would expect it to burst due to overwhelming flooding of water. Would this result occur more quickly if the paramecium was in water with a high salt concentration or in water with a low salt concentration? F 400

72. Water with a low salt concentration F 400

73. How can you explain the observed relationship between salt concentration and rate of contractile vacuole contraction? F 500 Salt Rate of contractile vacuole contractions/minute Very high2 High8 Medium15 Low22 Very low30

74. F 500 As salt concentration increases, there is less water flooding the cell due to osmosis (the solution is hypotonic to the cell, but becomes less so as the concentration of salt increases), therefore the contractile vacuole does not need to contract as often.

76. A selectively permeable membrane separates the solutions in the arms of the U-tube shown below. The membrane is permeable to the water and to solute A but not to solute B. Forty grams of substance A and 20 grams of substance B have been added to the water on side 1 of the U – tube. Twenty grams of substance A and forty grams of substance B have been added to the water on side 2 of the U-tube. Click on screen to continue When the system reaches equilibrium, how many grams of substance A will be on solution on side 1 of the U- tube?

77. Click on screen to continue 30 grams of solute A will be in side 1 at the end of the experiment
