Regina has been growing sunflowers in her backyard so she can harvest their seeds. The sunflowers are all growing in the same type of soil and receive the same amount of sunlight. Regina has also provided them all with the same amount of water. So far, the sunflowers have all grown the same amount.

Regina's grandfather comes to visit, and he tells Regina that the flowers will produce more seeds if she gives the flowers Fertilizer X. Regina would like to try the fertilizer, but it is very expensive. She decides to test the fertilizer in a scientific investigation before purchasing enough for all of the sunflowers.

Which of the following questions can Regina answer through a scientific investigation in order to test her grandfather's claim?
A.
Will Regina's grandfather be upset if she uses a cheaper fertilizer that works as well as Fertilizer X?

B.
Will providing sunflowers with Fertilizer X cause the flowers to produce more seeds?

C.
Will providing sunflowers with Fertilizer X result in more attractive flowers?

D.
Would it be wiser to use Fertilizer X on vegetable plants since it is so expensive?

Answer:

B.

Will providing sunflowers with Fertilizer X cause the flowers to produce more seeds?

Step-by-step explanation:

The question B is a sort of untested idea. It is the ideal hypothesis for Regina to test and see if the brand of the fertilizer will improve her sunflower seed production.

To scientifically carryout this test, Regina must set up an experiment. The experiment will help her affirm her grandfather's observation about the fertilizer.

The dependent variable here is the yield of the sunflower as we know. The sunflower will produce more seeds based on how nourished it is with available nutrients.

In her experiment, she can use the normal soil, soil with fertilizer x and maybe organic manure mixed with soil to compare different results. She then proceeds to plant her seed and on the long run observe the output.

From the result of her experiment, she can then conclude on her hypothesis. With the experiment, she can prove wether the fertilizer will improve the yield of the seeds or not.
