Question

Some species of plants that grow best in shade are used in an experiment. The plant species are divided into control groups and experimental groups. All groups are grown under identical conditions except that the experimental groups are given daily doses of direct sunlight. At the end of one month the growth of the control and experimental groups is compared.

Which of the following is the most likely hypothesis for the experiment described above?

A. Vegetation that grows in shady areas requires more water than vegetation in non-shady areas.
B. Direct sunlight causes the soil to have more space for vegetation.
C.
Vegetation near shaded areas requires more direct sunlight than offered.
D. Direct sunlight affects some types of vegetation that grow best in shady areas.

PLEASE ANSWER FAST!!!

Answer 1

D would probably be the best answer. Answer B doesn't make sense. Answer a doesn't take in the fact that different plants need different amounts of water which is also with answer C. Answer D is the most logical that resonates with the experiment. They are trying to see the effects of putting plants that like shades in the sun and see if it'll adapt or die.

Answer 2

The correct answer is option D.

Step-by-step explanation:

In the given experiment the variables are shade and direct sunlight for the experimental group of plants while the shade is variable for all the group of plants that grow best in shade.

According to the given information option, A and option B are incorrect in terms of different variables. Different vegetation requires a different dose of direct sunlight can not be generalized, so option c would not be answer.

Thus, the correct answer is option D.
