Answer (1)
Answer:In Christian's experiment:- Independent variable: The brand of fertilizer (since this is what he is changing between the two pots).- Dependent variable: The corn plant's fruit yield (since this is what he is measuring or observing).- Controlled variables: The amount of fertilizer, water, and sunlight given to each corn plant (since these are kept the same for both plants to ensure a fair test).
