1)Control Group - Group that does not receives the treatment.
2)Experimental Group - Group that receives the treatment.
3)Constant - The variable you keep the same.
4)Independent Variable - The variable you control.
5)Dependent Variable - It depends on the independent variable.
Example:
You want to know how much taller plants will grow with fertilizer. You do an experiment. Flower A receives fertilizer but flower B does not. Both flowers receive the same amount of water and sunlight. The control group would be flower B, the constants would sunlight and water, the independent variable would be the fertilizer., the dependent variable would be the plant's height, and the experimental group would be flower A.
DNA is like the instruction manual for building and operating a cell.
Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
There are so many examples for that in different areas, like biology experiment carried out in our lab recently.
