a scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. in this experiment the independent variable is?
○ the number of plants in the water
○ the amount of salt in the water
○ the temperature of the water
○ the water

Explanation:

In an experiment, the independent variable is the factor that the scientist changes or manipulates. Here, the scientist is changing the amount of salt in the water to see its effect on the number of plants. The number of plants is the dependent variable (changes based on the independent variable), and the temperature of the water and the water itself are not the variables being manipulated in this context.

Answer:

B. the amount of salt in the water
