Question

highlight the independent variable.
pea plant clones are given different amounts of water for a three - week period. first pea plant receives 400 milliliters. second pea plant receives 200 milliliters. third pea plant receives 100 milliliters. fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. the height of the pea plants is recorded daily.

Explanation:

In an experiment, the independent variable is the factor that is manipulated or changed. Here, the amount of water given to each pea plant (400 milliliters, 200 milliliters, 100 milliliters, or natural water intake) is what's being varied to observe its effect on the height (dependent variable) of the pea plants. So the independent variable is the amount of water.

Answer:

The amount of water (given to the pea plants)
