He asks if you will test it with him. You get in, and there is an immediate glitch—the date readout fails so that when you land, you are not sure what era you are in. Your professor begins to panic, but you see something that tells you are in the Cenozoic era. Which of the following could it be? A) a rabbit eating a daisy B) a water lily floating in a pond C) masses of green ferns with dragonflies hovering above them D) a bee pollinating a flower 12) You are the lucky student of a wacky professor who develops a time machine. He asks if you will test it with him. You get in, and there is an immediate glitch—the date readout fails so that when you land, you are not sure what era you are in. As your time machine lands, you see an unusual landscape before you. As you open the door, you realize you cannot breathe. You quickly shut the door, realizing you are in the ________. A) Archaean eon B) Cambrian period C) Cenozoic era D) Mesozoic era 13) An early consequence of the release of oxygen gas by plant and bacterial photosynthesis was to ________. A) change the atmosphere from oxidizing to reducing B) make it easier to maintain reduced molecules C) cause iron in ocean water and terrestrial rocks to rust (oxidize) D) prevent the formation of an ozone layer 14) Which of the following characteristics are expected in the first animals to have colonized land? I) They were probably herbivores (ate photosynthesizers). II) Animals had four appendages. III) Animals had the ability to resist dehydration. IV) Animals had lobe-finned fishes as ancestors. V) Invertebrates A) III only B) III and V C) I, III and V
