A school of psychiatric thought concerned with the medical treatment of mental disorders; especially, through medication, and emphasizing the relationship between behavior and brain function and the search for physical causes of mental illness.

The study of the effect of time on biological events, especially repetitive or cyclic phenomena in individuals.

1. A structure of dense material; such as, concrete or lead, around a nuclear reactor to protect against radiation.
2. a mass of absorbing material; for example, concrete or lead, placed around a reactor or radioactive material to reduce the radiation to a level safe for humans.

Any form of treatment for abnormal behavior that alters the individual's physiological processes, including electric shock treatment, surgery, etc.

The nutritional effectiveness of the protein in a given food, expressed as the percentage used by the body of either the total protein consumed or the digestible protein available.

Warfare that makes use of bacteria, viruses, toxins, etc., to disable or to destroy people, domestic animals, and food crops.

Able to sustain organic life.

Specifically, a term for areas of land and water capable of supporting photosynthesis at sufficient rates so as to provide economically useful concentrations of biomass.

Marginal and unproductive regions are generally excluded; such as, deserts, tundra, and the deep oceans.

Medicinal preparations made from living organisms and their products, including sera (serums), vaccines, antigens, antitoxins, etc.

Commercial products derived from biotechnology.

1. The interpretation of human life from a strictly biological point of view.
2. The use or emphasis of biological principles or methods in explaining human social behavior.

1. A specialist or expert in biology or one who studies biology.
2. A scientist who studies living organisms.
3. A scientist devoted to the study of organisms and their relationships to their environments and the underlying mechanisms that govern how those organisms work.

A cell of biologists.

The intelligent power displayed in organic activities.

1. The science concerned with the phenomena of life and living organisms.
2. The science of physical life; the division of physical science that deals with organized beings or animals and plants, their morphology, physiology, origin, and distribution.
3. The study of living organisms, including their structure, function, evolution, interrelationships, behavior, and distribution.
4. The study of human life and living.
5. The study of the properties and history of living organisms and of their interactions with the non-living world.

Using physics as a model, biologists have attempted to find universal processes and properties of all organisms that can be applied to all forms, despite the apparent diversity of life.

Living organisms are affected by and affect the non-living world strongly. The study of the history of the earth and its atmosphere is inseparable from the study of biology.
