A branch of anthropology that deals with humans as biological organisms, including areas such as primatology, human genetics, human ecology, paleoanthropology, and fields of applied anthropology such as anthropometrics and forensic anthropology.
A discipline in which the concepts of human biology are integrated with anthropological archeology.
Determination of the potency or concentration of a compound by its effect upon animals, isolated tissues, or microorganisms, as compared with an analysis of its chemical or physical properties.

2. The science dealing with the substances present in living organisms and with their relation to each other and to the life of the organism; biological or physiological chemistry.

Biochemistry includes the chemical reactions of living cells. It is based on the idea that all of life can be understood as chemistry. Situated between biology and chemistry, the field of biochemistry relates to all branches of chemistry and biology, ranging from genetics to physical chemistry, from medicine to agriculture, from nutrition to biotechnology.
