Quantum theory is a fundamental theory that describes the nature and behavior of matter and energy on the atomic and subatomic levels. Neils Bohr and Max Planck are the fathers of quantum theory, and both received Nobel prizes in Physics for their work on quanta. Einstein is the third founder of quantum theory who described light as quanta in his theory of the photoelectric effect and also won the Nobel Prize in 1921. Biology, on the other hand, is a discipline of science concerned with the study of living creatures and their vital processes. This area is concerned with all elements of life that are physicochemical. All living systems are made up of molecules, and quantum mechanics can describe all molecules.
