(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.

marine biologist (s) (noun), marine biologists (pl)
An individual who specializes in the branch of the living organisms that inhabit the sea: Jim's uncle was a marine biologist who spent much of his life either in the water engrossed in rare fish or in front of his computer reading about the newest discoveries in ocean life.
marine biology (s) (noun) (no pl)
A branch of biology that deals with the living organisms that inhabit the sea: Since Mary lived near the ocean, she wanted to study marine biology and learn as much as possible about life in the vastness of the Pacific.
marine biomass (s) (noun) (no pl)
A collective term for all organic substances of marine origin: Marine biomass can be exemplified by large seaweeds which are utilised in producing the manufactured kelp.
The study of how mechanical stimuli regulate biological processes. The mechanobiology of bone and cartilage lies at the heart of two of the most common skeletal diseases in the elderly: osteoarthritis and osteoporosis.

Cells are sensitive to mechanical force, and respond in a variety of ways, many of which are beneficial, but others that contribute to disease.

While biologists have contributed greatly to our understanding of the biochemical signaling pathways that transmit these responses, little progress has been made in identifying the initiating event in which a mechanical force is first transduced into a biochemical signal.

Mechanics regulates biological processes at the molecular, cellular, tissue, organ, and organism levels.

Mechanical loading can influence cell proliferation, differentiation, and metabolism; and as such, plays a crucial role in the growth, adaptation, regeneration and engineering of living tissues.

Several mechanisms have been proposed, and some have been characterized, but there is still much to learn.

In the process of studying the interactions between force and biology, this new field of mechanobiology is now being studied in various universities.

Pertaining to the biological aspects of medicine.
1. The normal degeneration and death of living cells; a normal mechanism in the constant turnover of many cell populations.
2. Dermatosis characterized by patchy degeneration of the elastic and connective tissue of the skin with degenerated collagen occurring in irregular patches, especially in the dermis.
Soil organisms of intermediate size, from about 40-50 mm in length to a size just visible with the aid of a hand lens (magnifier).
A many-celled organism (metaphyte and metazoon).
1. Dependence of one organism on another for its existence.
2. A relationship between two organisms in which only one of the partners benefits.
3. Either a condition of symbiosis in which one symbiont sets the stage for the arrival of the other or a mutual association of two organisms of which one is thought to benefit without detriment to the other.
4. A symbiotic relationship in which one organism modifies the environment before the second one is able to live in it.
A microaerophilic micro-organism.
Any micro-organism; especially, a bacterium. Also: a micro-organism.
Caused by micro-organisms.
Someone who specializes in the science of microbiology or the science concerned with micro-organisms.
