Ms. green's biology students were studying cellular respiration. using baking yeast to test the rate of fermentation, student groups mixed yeast with different manipulated variables. the groups used the height of the carbon dioxide bubbles produced in a test tube to determine which variable(s) produced the highest rate of fermentation. students hypothesized that adding a sixth test tube would produce the greatest amount of carbon dioxide. the answer is warm water, yeast, and lactose.

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.
