Question

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

Answer 1

The correct is  B. I,II,III

Answer 2

The correct answer will be options:

1. Identifying hybrid strains of plants that mature faster

2. Helping farmers achieve better yields per acre

3. Getting more food or fiber at less expense

Step-by-step explanation:

Phosphorus is a macro-nutrient of plants which is required by the plant in higher amount. Phosphorus is one of the limiting nutrients of plant that is if absent will prevent the growth of the plant.

In the given experiment to measure the uptake of phosphorus by roots from soil can be observed by measuring the growth of the plant, yield per acre and the amount of fiber in the plants.

Thus, the selected options are the correct answer.
