Answer:
Independent variable: AMOUNT OF SUNLIGHT
Dependent variable: HEIGHT OF PLANTS
Experimental group: PLANTS KEPT UNDER BRIGHT SUN LAMPS ALL NIGHT
Control group: PLANTS THAT RECEIVED NORMAL AMOUNT OF SUNLIGHT
Explanation:
Independent variable refers to the variable that is manipulated or changed in an experiment in order to effect a measurable response. In this case, the independent variable is the VARYING AMOUNT OF SUNLIGHT.
Dependent variable is the variable that the experimenter measures or the variable that responds to changes made to independent variable. The dependent variable in this case is the HEIGHT OF PLANTS measured.
Experimental group is the group in an experiment that receives the experimental treatment. In this case, the PLANTS KEPT UNDER BRIGHT SUN LAMPS ALL NIGHT is the experimental group.
Control group is the group that does not receive any experimental treatment/independent variable. In this case, the PLANTS THAT RECEIVED NORMAL AMOUNT OF SUNLIGHT is the control group.
