Final answer:
The height of the plant represents the dependent variable (DV) in the experiment studying the effect of music volume on plant growth.
Step-by-step explanation:
In an experiment studying the effect of music volume on plant growth, the height of the plant represents the dependent variable (DV). The independent variable (IV) would be the music volume, which is what the researcher is manipulating in the experiment. The constants (C) in the experiment would be factors that are kept the same across all conditions, such as the type of plant, the amount of water and sunlight provided, the temperature, and the soil type.
