The correct answer is A. Seed growth

Explanation:

Experiments often involve two main variables: the independent variable and the dependent variable. In an experiment, the dependent variable is always the main factor being studied; also, this is "dependent" because it is affected by other factors. In the case presented, the dependent variable is seed growth because this is the specific phenomenon that is being analyzed. Moreover, this factor is affected by the changes in pH. On the other hand, the pH, which is the second factor is the independent variable because this is not affected by the first variable and it is manipulated on purpose.

Lynna [10]

Answer:

It reveals that light is a wave

Explanation:

Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.

This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.
