Question

a. in the process of growing sunflowers, a different liquid (milk, lemon juice, sprite) is applied to 3 sunflowers. a normal sunflower is given water. the sunflowers are the same age, in the same soil and in the same pot.

i. control group =

ii. independent variable =

iii. dependent variable =

iv. constants =

Explanation:

i. Control Group

The control group in an experiment is the group that is not exposed to the independent variable and is used for comparison. Here, the sunflower given water is the control as it represents the normal condition without the experimental liquids (milk, lemon juice, sprite).

The independent variable is the factor that is manipulated in an experiment. In this case, the different liquids (milk, lemon juice, sprite) applied to the sunflowers are what's being changed, so it's the independent variable.

The dependent variable is the outcome that depends on the independent variable, usually related to the response of the subject. For the sunflower experiment, the growth of the sunflowers (or how the sunflowers grow) depends on the liquid applied, so it's the dependent variable.

Answer:

The sunflower given water.

ii. Independent Variable
