Answer:

The independent variable is "controlled" or held constant in the control group. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an experiment.

Answer:

Explanation:

A control group is a standard group which is used for the purpose of the experiment. It does not receive any manual treatment by the experimenter. Instead it is kept as a standard for comparison of the other variables.

The multiple control groups are used in the experiment so as to increase the accuracy, consistency and reliability of the results. As if one control group contains contaminants it may produce errors in the experiment. To avoid error and enhance error and increase accuracy multiple control groups are used.

If all green plants in the world were distroyed which atmospheric gas will increase

Mila [183]

Trees are a crucial part of the carbon cycle, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
