What is the dependent variable in this experiment?
What is the control group in this experiment?

Answer 1

The correct answer is :

The independent variable -types of fertilizers

The dependent variable - the growth of plants

The control group - plant gets water only

Step-by-step explanation:

In any scientific experiment or study, the subject of the research gets a variable treatment that is manipulated or changed to check the different variable which shows the response to change made, variables that manipulated called as the independent variable. Types of different fertilizers are independent variable in this experiment.

The variable that shos response to a change in the independent variable called the dependent variable, the response in this study is the growth of the plants.

The control group in any study is the group that did not receive the treatment other groups receive, that is plants receive water only.
