Match the definition with the correct terma. independent variable b. control group c. experimental group d. constant variable e. dependent variable 1. this is the variable that scientist change a the beginning of the experiment. 2. this is the variable that scientist measure at the end of an experiment. 3. this is the group that has no change to the independent variable. 4. this is the group that has a change to the independent variable. 5. this is a group of variables that you set at the same value for all groups and all trails.

A. Independent Variable-

An independent variable is the variable that is changed or controlled in a scientific experiment in order to test the effects on the dependent variable. Therefore, option 1. This is the variable that scientist change at the beginning of the experiment is the correct definition for independent variable.

B. Control Group-

A control group is a standard to which comparisons are made in an experiment. This group does not bring change in the dependent and independent variable but used as a benchmark for comparison. Therefore, option 3. This is the group that has no change to the independent variable is the correct definition for control variable.

C. Experimental Group-  

An experimental group is a group that receives treatment in an experiment. Independent variable are variables that receives change so as to determine the effects on the dependent variable in an experimental setup. Therefore, option 4. This is the group that has a change to the independent variable is the correct definition for experimental group.

D. Constant Variable-

A constant variable is the one whose value once assigned in an experiment remain the same in all trials. Therefore, option 5. This is a group of variables that you set at the same value for all groups and all trails is the correct definition for constant variable.

E. Dependent Variable-

A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is dependent on the independent variable. Therefore, option 2. This is the variable that scientist measure at the end of an experiment is the correct definition for dependent variable.

the answer is c.) there is a warm front in region a and a stationary front in region b.
