control
Control.
Variable
In an experiment, the control is the group to which nothing is done. It serves as a baseline to measure any changes that might occur to the group or groups that to which external variable is applied.
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.
Your question is not clear. The only help that I can offer is this: When all else remains the same, and only the variable changes, this is called "ceteris paribus", which is Latin for "all else remains the same", approximately. So in an experiment you might say, "If we change the variable, ceteris paribus, I anticipate this outcome will occur." Hope this helps.
