Question

ms. riveras biology class wanted to investigate how the amount of sunlight affects the growth of bean plants. they planted identical bean plants in separate pots and exposed each group to different amounts of sunlight per day: 2 hours, 4 hours, 6 hours, and 8 hours. each week, they measured and recorded the average height of the plants in centimeters over a 5 - week period. below is the line graph showing the average height of plants receiving 6 hours of sunlight per day over the 5 weeks. plant height (cm) vs. week 6. the select variable is amount of sunlight, while the select variable is the growth of the plant.

Explanation:

In an experiment, the independent variable is the factor that is deliberately changed or manipulated. Here, the amount of sunlight is being changed (2, 4, 6, 8 hours). The dependent variable is the factor that responds to the change in the independent variable. The growth of the plant (measured by height) is what is being observed and is dependent on the amount of sunlight.

Answer:

The independent variable is amount of sunlight, while the dependent variable is the growth of the plant.
