Question

A scientist wants to determine which fertilizer is more effective—Fertilizer X or Fertilizer Y. The best way for her to proceed would be to design an experiment with A. three groups of plants—a group fertilized by X, a group fertilized by both X and Y, and a control group with no fertilizer. B. two groups of plants—a group fertilized by X and a control group with no fertilizer. C. three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer. D. two groups of plants—a group fertilized by Y and a control group with no fertilizer. what would the answer be? btw this is a science question

Answer 1

C. three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer.

The scientist should design an experiment with three groups of plants—a group fertilized by X, a group fertilized by Y, and a control group with no fertilizer. All three groups should receive the exact same treatment in the experiment, except for how they are fertilized. This will allow the scientist to study the effects of the different fertilizers on the plants.

Answer 2

C because we are testing the effectiveness of Fertilizer X and Y and using no fertilizer can help determine if that would be better than using a fertilizer. Additionally, a control group of no fertilizer would be the third plant as that is considered normal for the experiment. Msg me for any more questions
