bio-, bi-, -bia, -bial, -bian, -bion, -biont, -bius, -biosis, -bium, -biotic, -biotical

(Greek: life; living, live, alive)

Don’t confuse this element with another bi- which means "two".

The most important things in life are not things.

biotelemetry
1. Study of the behavior and activity of organisms using remote detection and transmission equipment; radio tracking.
2. The technique of monitoring vital processes and transmitting data without wires to a point remote from the subject.
3. The tracking of a free-ranging animal, or the monitoring of one or more of its physiological conditions, by beans of electronic equipment that receives signals from a radio transmitter or similar device attached to, or embedded in the animal.
bioterror (s) (noun)
The use of biological agents for terrorism.

The term bioterror is often used loosely to describe nuclear, biological, and/or chemical (NBC) terrorism.

The U.S. government is especially worried about the Big Six bioterrorism threats: anthrax, smallpox, plague, tularemia, botulism toxin, and viral hemorrhagic fevers (like the Ebola virus).

While less well-known than the other diseases, tularemia and botulism toxins could conceivably be aerosolized, causing severe respiratory illness and paralysis, respectively.

bioterrorist (s) (noun), bioterrorists (pl)
A terrorist who uses biological weapons: "Not only water supplies are susceptible to such deliberate contamination; so, too, is much of the air we breathe."

"Skyscrapers, tunnels, subways, and their requisite heating and air-conditioning systems provide targets and also ways of attack for would-be bioterrorists."

biothanatos
An older term for suicide.
biotherapeutics
biotherapy
1. Treatment using biological agents, almost always those made by genetic engineering. Genetic engineering is central to modern biotherapy’s backbone: pharmaceutical biotechnology. Pharmaceutical biotechnology involves using microorganisms, macroscopic organisms, or hybrids of tumor cells and leukocytes.
2. Virtually all biotherapeutic agents in clinical use are biotech pharmaceuticals. A biotech pharmaceutical is simply any medically useful drug whose manufacture involves microorganisms or substances that living organisms produce (e.g., enzymes). Most biotech pharmaceuticals are recombinant‹that is, produced by genetic engineering. Insulin was among the earliest recombinant drugs.
3. In psychology, any form of treatment for abnormal behavior that alters the individual’s physiological processes; such as, electric shock treatment or surgery.
4. The treatment of disease with biologicals, that is, materials produced by living organisms.
biothermal
Pertaining to the inter-relationship of temperature and living organisms.
biothesiometer
An instrument for measuring the vibratory-perception threshold.
biotic
1. A reference to common life; secular.
2. Pertaining to life or living organisms; caused by, produced by, or comprising living organisms.
biotic environment
1. The biological factors acting on an organism, which arise from the activities of other living organisms, as distinct from physical factors.
2. The living organisms of a community habitat or environment.
biotic factor
An environmental factor associated with, or resulting from, the activities of living organisms.
biotic potential
1. The maximum possible number, or intrinsic rate of natural increase, of offspring produced by an individual under ideal conditions.
2. The capacity of a population of living organisms to increase under ideal and optimal environmental conditions.

Environmental factors; such as, limitation of resources, predation, and disease mean that the biotic potential is seldom realized.

biotics
The science concerned with the functions of life, or vital activity and force.
biotome
1. The study of animal and plant structure by dissection; vivisection.
2. A biopsy instrument passed through a catheter into the heart to obtain pieces of tissue for diagnosis.
biotomy
