Answer:
The correct answer will be-
1. independent variable- the type of fertilizer
2. dependent variable- height of the plants
3. control group- The quadrant without any fertilizer treatment
4. Importance of control group- acts as reference to the experimental group as is performed without the key component in natural conditions.
Explanation:
A scientific experiment contains three types of variable and is divided into two types of group of samples.
The variables studied in the experiment are;
1. Independent variable: parameter which changes or is induced to change as per the demand of the experiment like the type of fertilizer in the experiment.
2. Dependent variable: parameter which depends on the independent variable and has to be studied in the experiment like the height or growth of the plant.
3. Control group: the group of samples left untreated in which the key component like fertilizer is not provided. So, the quadrant without any fertilizer treatment will be considered the control group.
