Controls are used in medicine simply to designed to minimize the effects of variables other than the independent variables in scientific experiment
<h3>Living organisms </h3>
Living organisms; be it plants or animals are any organic or living system composed of cells and function as an individual entity.
All living organisms share a number of key characteristics or functions such as movement, respiration, homeostasis, reproduction, growth, evolution, competition and others.
Animals and plants also posess systems such as the digestive, skeletal, transport, nervous, excretory, respiratory and reproductive system.
Living organisms are also taxonomically classified as either unicellular microorganisms or multicellular plants and animals
So therefore, controls are used in medicine simply to designed to minimize the effects of variables other than the independent variables in scientific experiment
