Which of the following steps of the scientific method describes the experimental setup?   One group of tomato plants are grown in the greenhouse with constant temperature of 22 degrees Celsius while the other group is grown in a greenhouse with a constant temperature of 30 degrees Celsius. The hypothesis is supported. The tomatoes grown at 22 degrees Celsius produce 25% more fruit than the tomatoes grown at 30 degrees Celsius. You observe that your tomatoes produce more fruit in the spring when temperatures are mild compared to tomatoes grown in the summer. Your hypothesis is that tomatoes will produce more fruit during the cooler season of spring.
