In ecology, that part of the lithosphere within which living organisms can exist: The biogeosphere is the region of the earth that reaches from the surface of the top crust down to the maximum depth in which organisms can live.

Scientists who investigate the aging process and who do scientific studies of the biological, psychological, and sociological phenomena that are associated with old age and aging: "Some biogerontologists promote the idea that aging is a programmed phase of decline following the plateau of maturity."

"When biogerontologists attempt to take cells from organisms, whether plants or animals, and grow them in test tubes, old age soon overtakes the cultures and the cells stop dividing, and so the cultures die."

A sub-field of gerontology (study of the social, psychological, and biological aspects of aging) that is concerned with the living processes of aging: "Biogerontology involves interdisciplinary research on biological aging's causes, effects, and mechanisms."

"Cells from old organisms are different from cells of young ones, and observations about how they differ are the basis of biogerontology, a science of the biology of aging."

A ceramic-glass material used as a bone prosthesis.

Living bone fuses with it because chemically it resembles hydroxyapatite (an inorganic constituent of bone matrix and teeth, imparting rigidity to these structures).

A sedimentary structure consisting of a fossilized remnant or mark formed in soft sediment by the movement of an animal and pressed in sedimentary rock.
