Explanation:

The independent variable is what is changed in an experiment. Here, it's whether or not the miracle - grow fertilizer is used. The dependent variable is what is measured as a result of the change in the independent variable, which is the weight of the tomatoes. Control variables are kept the same throughout the experiment to ensure that only the independent variable affects the dependent variable. So, kind of tomato, water, sunlight, and location of tomatoes are control variables.

Answer:

Independent variable: miracle grow
Dependent variable: weight of tomatoes
Control variable: kind of tomato, water, sunlight, location of tomatoes
