Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ____
A
The type of plant
B
The amount of sunlight
C
The type of music
D
The type of liquid
Explanation: 

Detailed explanation-1: -Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.

Detailed explanation-2: -The experiment shows that salt is damaging to plants. The damage increases as the salinity increases. In pure freshwater, cut vegetables should remain largely unchanged for several days without showing much sign of wilting. The higher the salt concentration in the water, the worse the plants will fair.

Detailed explanation-3: -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.
