This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Medical biology is a field of biology that has practical applications in medicine, health care, and laboratory diagnostics. It includes many biomedical disciplines and areas of specialty that typically contains the "bio-" prefix such as: molecular biology, biochemistry, biophysics, biotechnology, cell biology, embryology,
Involution is the shrinking or return of an organ to a former size. At a cellular level, involution is characterized by the process of proteolysis of the basement membrane (basal lamina), leading to epithelial regression and apoptosis, with accompanying stromal fibrosis.
Cell biology – also called cytology, is a branch of biology that studies the structure and function of the cell, which is the basic unit of life. [110] Cell biology is concerned with the physiological properties, metabolic processes, signaling pathways , life cycle , chemical composition and interactions of the cell with their environment.
The most well known examples are antibiotic resistance in the medical field along with better-known laboratory experiments documenting evolution's occurrence. Natural selection is tantamount to common descent in that long-term occurrence and selection pressures can lead to the diversity of life on earth as found today.
The typical age of legal majority is 18 years in most contexts, although the definition of majority may vary by legal rights and country. Human adulthood encompasses psychological adult development.

Life, as everyone knows, is full of changes that occur with regularity from infancy through the senior years.When you reach retirement age, it’s important to know how certain life changes can ...
Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature
