An experiment is being done to determine how light affects the growth of small zinnia plants. One plant is placed in full sunlight, the second in a shaded area, the third in an unlit closet. The hypothesis of this experiment could be:

• Plants grow differently under different conditions.
• Zinnia plants in direct sunlight grow taller than zinnia plants in little or no sunlight.
• Many things, including sunlight, affect the growth of a plant.

The part of the experiment that remains the same for the control and experimental group.

• constants
• control
• independent
• dependent
