Maturity (geology), in petroleum geology; Maturation, as a threat to internal validity of an experiment; Tissue maturation, an aspect of developmental biology The final stages of cellular differentiation of cells, tissues, or organs
A life history strategy is the "age- and stage-specific patterns" [2] and timing of events that make up an organism's life, such as birth, weaning, maturation, death, etc. [3] These events, notably juvenile development, age of sexual maturity, first reproduction, number of offspring and level of parental investment, senescence and death, depend ...
Adult development encompasses the changes that occur in biological and psychological domains of human life from the end of adolescence until the end of one's life. Changes occur at the cellular level and are partially explained by biological theories of adult development and aging. [1]
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
Some tortoises show negligible senescence. Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. [1]
It is given this name in eudicots because most plants from this group have two cotyledons, giving the embryo a heart shaped appearance. The shoot apical meristem is between the cotyledons. Stage IV, in the illustration above, indicates what the embryo looks like at this point in development. 5 indicates the position of the cotyledons.
And like DNA damage, it can promote senescence by triggering a prolonged cell cycle arrest. [5] While a typical increase in cell size controls for concentrations of cell cycle activators, [ 1 ] [ 12 ] an excess of growth can drive a permanent halt on cell proliferation as a result of various mechanistic interactions with cell-cycle signaling ...
Haldane mirrors Gould's hypothesis by stating a "major evolutionary trend in human beings" is "greater prolongation of childhood and retardation of maturity." [ 3 ] Delbert D. Thiessen said that "neoteny becomes more apparent as early primates evolved into later forms" and that primates have been "evolving toward flat face."
