Question

a student completed an experiment that compared the amount of nitrogen given to a tomato plant to how many tomatoes the plant produced. which of the following is the best axis label and placement for the independent variable? amount of nitrogen given (in kilograms), x - axis amount of tomatoes produced (in kilograms), x - axis amount of nitrogen given (in meters), y - axis amount of tomatoes produced (in meters), y - axis

Explanation:

The independent variable is the variable that is manipulated or changed in an experiment. Here, the amount of nitrogen given to the tomato - plant is being changed to observe its effect on the amount of tomatoes produced. So, the independent variable should be labeled on the x - axis. And the amount of nitrogen given should be in kilograms (a unit of mass for the nutrient), while the amount of tomatoes produced should be on the y - axis.

Answer:

Amount of Nitrogen Given (in kilograms), x - axis
