We humans are on track to more than double the atmospheric co2 concentration that existed for the few millennia before the industrial revolution. if we could cause just a doubling and then hold the co2 level constant for the next thousand years, we very likely would see: a. the earth would cool and cool, eventually causing a new ice age. b. the earth would warm many tens of degrees, and then the temperature would stabilize at that new, warmer level. c. the earth would cool a few degrees, and then the temperature would stabilize at that new, cooler level. d. the earth would warm a few degrees, and then the temperature would stabilize at that new, warmer level. e. the earth’s temperature would remain the same as it was before the start of the industrial revolution

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
