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.

bioinstrument (s) (noun); bioinstruments (pl)
1. A sensor or device usually attached to or embedded in the human body or other living animal to record and to transmit physiologic data to a receiving and monitoring station.
2. Devices for recording and transmitting physiological data or to display information about the body’s functions.
3. The use of sensors and other instruments to record and transmit physiological data from people or other living things; such as, in space flight.
biokinetics
1. The study of the growth changes and movements that developing organisms undergo.
2. The science of the movements within developing organisms.
biolinguistics (s) (noun)
1. The study of the biological underpinnings of language; such as, the factors that enhance or retard language development and the neurophysiology of language disorders.
2. The study of language functions as related to or derived from biological characteristics of an organism.
biolistics
The technique of introducing DNA into a cell by firing minute DNA-coated particles (for example, of gold) into the cell using a device powered by pressurized helium (the ballistic gun or “gene gun”).
biolite
Any rock or group of minerals formed from organic material or by the action of organisms.
biolith
1. A rock of organic origin.
2. A rock that is formed from or by organic material, either by noncombustible, inorganic processes that form an acaustobiolith, or by combustible, organic processes that form a caustobiolith (a combustible organic rock).
biolithite
Any limestone of an organic nature such as a reef rock or stromatolite.
biologic
1. Referring to biology.
2. Pertaining to the products and operations of applied biology.
3. Any virus, therapeutic serum, toxin, antitoxin, or analogous product of plant or animal origins used in the prevention, diagnosis, or treatment of disease; for example, vaccines, and blood plasma products.
biological
1. Pertaining to living organisms or life processes.
2. A reference to the products and operations of applied biology.
3. Any substance, as a serum or vaccine, derived from animal products or other biological sources and used to treat or to prevent disease.
biological accumulation (s) (noun), biological accumulations (pl)
The collections within living organisms of toxic substances occurring in the encircled areas.
biological anthropology (s) (noun), biological anthropologies (pl)
See "bioanthropology" for the applicable definition for this biological anthropologyentry.
biological child
Any child conceived rather than adopted by a specified parent, and therefore, carrying genes from the parent.
biological clock
1. An internal time-measuring mechanism which helps to adjust an organism's daily activities, seasonal activities, or both in response to environmental cues.
2. The internal mechanism of an organism that regulates circadian rhythms (daily cycles of activities) observed in many living organisms and various other periodic cycles.

The mechanism of the biological clock has long proved elusive; however, a molecular basis for such a clock in the fruit fly Drosophila has been discovered, and similar mechanisms may well apply in other organisms.

It is based on the cyclical rise and fall in the concentrations of certain proteins which form part of a negative feedback loop that controls transcription of their own genes.

biological community
All of the organisms inhabiting a given area.
biological concentration
