Asked by FOR A SCIENCE TEACHER

Hey! I am doing a biology lab in which we take liver and sand and place it in a test tube, to see it if it will react with hydrogen peroxide. One of the test tubes just has sand in it, and no reaction occurs. This is because the sand acts as a control and is inorganic meaning it won't react with the enzymes in the liver. My question, what exactly does it mean that the sand is a control? Thanks

This is my answer: the control means that it controls enzyme activity (but I am not sure)

Thanks !
