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.

Mary Beth bought 15 ghost shrimp. She put 5 in a small fish bowl, 5 in a larger tank, and 5 in an artificial pond in her backyar

Kaylis [27]

Answer:

Initial age of ghost shrimp and water temperature

Explanation:

In an experiment, there are several variables (alterable factors) that determine the outcome of the experiment. A CONTROLLED variable or CONSTANT is a variable that is kept constant or unchanged throughout the experiment. The constant is not changed because it can affect the other variables (outcome) of the experiment.

For this experiment conducted by Mary Beth on the effect of size of the tank on the size of the shrimp after 6months, the constants are INITIAL AGE OF GHOST SHRIMP and WATER TEMPERATURE. This is so because the ghost shrimps of the same initial age must be used to start the experiment, so as to be able to measure the actual effect on the growth. Also, the water in the respective tanks must be the same Temperature so that one experimental group will not be favored over another.
