When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

A	Dependent
B	Independent
C	Control
D	Compound

Explanation:

Detailed explanation-1: -Score on the test. When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer? Independent.

Detailed explanation-2: -Independent variable: amount of sunlight. Dependent variable: growth of plant. Controlled variables: type of plant (genetic makeup), number of seeds, availability of water, time.

Detailed explanation-3: -In the plant experiment shown in the Figure below, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer-some plants will get fertilizer, others will not.
