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 (the standard or normal condition) is the control group as it provides a baseline to compare the growth of sunflowers with other liquids.

The independent variable is the factor that is manipulated or changed in an experiment. In this case, the type of liquid (milk, lemon juice, sprite, water - but water is for control) applied to the sunflowers is what's being varied, so the independent variable is the type of liquid.

The dependent variable is the factor that is measured or observed to see the effect of the independent variable. Here, the growth of the sunflowers (like height, number of leaves, etc., though not specified, the growth is what's affected by the liquid) is the dependent variable as it depends on the type of liquid used.

Answer:

The sunflower given water

ii. Independent Variable
