The hypothesis in a seed germination experiment is: light is necessary for lettuce seed germination. groups of lettuce seeds are placed in light with warm temperatures and adequate moisture. another set of identical seeds is placed in the dark under the same conditions. in this experiment, what is the independent variable?

Independent Variables are: The amount of warm temperatures and adequate moisture that plant received.

Explanation:

Independent and dependent variables are commonly used variables.

The variable that we can change is called the Independent variable.

 The dependent variable depends upon the independent variable, as we change the value of the independent variable the value of the dependent variable is also get changed.

Here we are interest to know that "Does a lettuce seeds are grown best in dark or light?"

Here the amount of warm temperatures and adequate moisture that plant received can be changed, so it is independent variable.

The plant's growth is dependent variable.
