Science question....best answer gets points!?

4. Meteorology is the study of weather. In many situations it is impossible to do real experiments with weather. For example, when trying to predict the path of a hurricane, it is impossible to create a hurricane in the laboratory for observation. Which of these would a scientist need to use to study large-scale events like hurricanes and earthquakes? (Points: 2) model atomic accelerator telescope centrifuge 5. An experiment is designed to test the effects of fertilizer on tomato plants. One group of plants is given fertilizer and another group is not. At the end of three weeks, the height of the plants is measured. Based on the measurements, the plants with the fertilizer grew taller. The scientist conducting the researcher concluded that fertilizer makes plants grow taller. In this experiment, what is the technical name for the tomato plants that did not get fertilizer?
