Astudent sets up an experiment with two groups of bacteria. one group is exposed to the normal amount of mercury found in the environment. the other group gets a larger dose. which term describes the normally treated group? control group independent group experimental group variable group

control group

Explanation:

In an experiment, the control group is one that does not receive the "factor" that is being tested in the experiment, and is maintained under normal circumstances.

In relation to the question above, we can see that an experiment was established with the objective of testing the results of exposing a group of bacteria to quantities of mercury greater than the quantities found naturally in the environment, that is, this experiment wanted to test the effect of large quantities of mercury in bacteria. For this reason, we can conclude that the group of bacteria that was subjected to normal amounts of mercury is the control group.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
