Answer:
This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?
Independent variable: ORGANIC AND CHEMICAL FERTILIZERS
Dependent variable: HEIGHT OF PLANT
Controlled variable: Same type of seed, water
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.
Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.
Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.

Hello.
There are a couple things needed for natural selection.
Natural selection is organisms become comfortable and changer where they are newly located. Where they can live and get more off springs.
First, You will need <u>heredity</u> which passes traits to an offspring.
Second, <u>reproduction</u> that is needed to to copy traits and give them to the offspring.
