Answer:

B. everything should remain the same between experimental groups

Explanation:

The control group, in one experiment, is characterized by individuals who will not receive the factor being tested in the experiment, but will also be evaluated at the same time points as the subjects in the intervention group. For example, if you have bean plants and want to do an experiment where you will evaluate the effectiveness of a fertilizer on bean plants, you will apply fertilizer on 9 bean plants while one plant will be maintained without fertilizing it. However all plants will be treated the same (except for fertilizer application) and will be evaluated in the same way. The fertilizer is the factor that is being tested in the experiment, the plant that did not receive it is the control group.

Alona [7]

Answer:

Water and ions are obtained from soil and glucose is obtained from leaves.

Explanation:

Water and ions are absorbed by the plant through roots from the soil whereas glucose is produced in the leaves during the process of photosynthesis. Vascular bundles such as xylem and phloem transported water, ions and glucose within the body. Xylem moves water from roots to the upper water of plants such as leaves, stem etc whereas phloem transported glucose from leaves to other parts of plant.
