• a student conducted an experiment to test whether talking to plants would help them to grow faster. he set up the following two groups: group 1: spoken to and hand watered group 2: not spoken to and watered with sprinklers after three weeks, the plants in group 1 showed much more growth than those in group 2. based on the results of this experiment, which is the best conclusion? they are valid because the student ran a controlled experiment. they are not valid because the student did not control all the variables that can affect plant growth. they are valid because the dependent variable caused a change in the independent variable. they are not valid because the time frame to grow a plant is too short.

• select the correct answer from each drop-down menu. a bird caught a fish on the waters surface and flew in a straight line diagonal to the water for 100 yards. then, it dropped the fish straight down. the fish landed at a spot 50 yards away horizontally from the point where the bird caught it. the bird flies at an angle of degrees from the water, and its height from the ground when it drops the fish is yards.
