Plants take up phosphorus-containing compounds from the soil through their roots. Scientists can add a small amount of radioactive phosphorus-32, which emits beta particles, to fertilizer and determine how fast phosphorus is taken up by the roots into the leaves. The results of this experiment can help scientists. From the list below, identify which outcomes can be obtained by applying the results of this experiment. I. Identifying hybrid strains of plants that mature faster. II. Helping farmers achieve better yields per acre. III. Getting more food or fiber at less expense. IV. Identifying different fungi that are affecting the growth of plants. A) I and II B) I, II, and III C) II, III, and IV D) I, II, III and IV
