Helen is studying the growth of two different types of plants. She planted two of each type of plant in locations with different levels of sunlight: full sun, partial shade, and full shade. For five weeks, Helen records the number of new leaves on each plant. Which of the following statements correctly describes the independent and dependent variables in Helen's experiment?

• The independent variable is the kind of plant, and the dependent variable is the amount of sunlight.

• The independent variable is the amount of sunlight, and the dependent variable is the number of new leaves.

• The independent variable is the amount of sunlight, and the dependent variable is the kind of plant.

• The independent variable is the number of new leaves, and the dependent variable is the amount of sunlight.
