86. What do you think would happen to a cell if minor DNA damage occurred that caused the cell to "pause" at a checkpoint during the cell cycle, and then the DNA damage could not be fixed? a. The cell would stay paused at that stage of the cell cycle indefinitely. b. This would not occur, since once initiated progression through the cell cycle cannot be stopped c. A macrophage will sense the problem and kill the cell. d. The cell would terminally differentiate. e. The cell would undergo apoptosis (programmed cell death).

85. An ecologist collects three related beetle species – one from a tropical rain forest, another from a desert and the third from the tundra. Back in the lab, she places all the beetles in a warm, dry environmental chamber and measures water loss across the cuticle. From highest to lowest rate of water loss, how would you expect the three species to rank? a. tropical rain forest > desert > tundra b. desert > tundra > tropical rain forest c. tundra > desert > tropical rain forest d. desert > tropical rain forest > tundra e. tropical rain forest > tundra > desert 86.
