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.

1. Formation of a chemical compound by enzymes, either in the organism (in vivo) or by fragments or extracts of cells (in vitro).
2. The production of organic compounds by living organisms.
3. Chemical reactions in which a living cell builds up its necessary molecules from other molecules which are present.
A living organism or any complete system of living things that can, directly or indirectly, interact with others.
1. A botanical term designating the systematic study of populations and species, especially by means of ecological or experimental methods.
2. The study of the relationships among groups of species using criteria such as morphology, biochemistry, and DNA comparisons, especially to determine the evolutionary history of a species (used with a singular verb).
3. The area of systematics in which experimental taxonomic techniques are applied to investigate the relationships between taxa.

Such techniques include serological methods, biochemical analysis, breeding experiments, and cytological examination, in addition to the more established procedures of comparative anatomy.

Evidence from ecological studies may also be brought to bear.

Biot's breathing, Biot's respiration
1. A form of breathing in which periods of apnea are interrupted by several consecutive deep breaths.

It is said to be a sign of meningitis.

2. Breathing marked by several short breaths followed by long, irregular periods of apnea.

It is seen in patients with increased intracranial pressure.

Named for Camille Biot, French physician, born in 1878.

These two terms are NOT based on the "bio" element; however, they are placed here to clarify any confusion someone might have when seeing the terms in use.

1. A collective term for the total animal (fauna) and plant (flora) life of a region.
2. The totality of all forms and species of living organisms within a certain area or habitat at a given time.
3. Plant and animal life in general or an area's flora and fauna.
1. The selecting and arranging activity of living cells.
2. The classification of living beings according to their anatomical characteristics.
1. The directed reaction of a motile organism towards (positive) or away from (negative) a biological stimulus.
2. The classification of living beings according to their anatomical characteristics.
biotechnical robot
A robot that can work only in conjunction with a human operator.
The practical application of discoveries in the biological sciences.
A professional who uses living organisms, or other biological systems, in the manufacture of drugs, or other products, or for environmental management; such as, in waste recycling.
biotechnology, biotech
1. The branch of technology concerned with the development and exploitation of machines in relation to the various needs of human beings.
2. The branch of technology concerned with modern forms of industrial production utilizing living organisms, especially micro-organisms, and their biological processes; including such ancient endeavors as the use of yeast in preparing bread for baking, and such modern concepts as genetic engineering.
3. The application of technology to biological processes for industrial, agricultural, and medical purposes.

Examples include bacteria; such as, Penicillium and Streptomycin are used to produce antibiotics and fermenting yeasts produce alcohol in beer and wine manufacture.

Genetic engineering now enables the large-scale production of hormones, blood serum proteins, and other medically important products.

Genetic modification of farm crops offers improved protection against pests, or products with novel characteristics; such as, new flavors, colors, or extended storage properties.
