Apr 9, 2024 · It can be physiological, which occurs in normal tissues or organs, or pathological, i.e., in disease states. In this article, we will consider how the sizes of cell populations are controlled, how cells and tissues can adapt in response to stressors and how these processes can result in disease.
adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations.
Jun 7, 2020 · Biological cells are adaptive. Change their environment and they respond. In homeostasis, a cell returns to a stable state after it has been perturbed. In evolution, a population of cells becomes better suited to new circumstances.

Jun 20, 2018 · An adaptation, or adaptive trait, is a feature produced by DNA or the interaction of the epigenome with the environment. While not all adaptations are totally positive, for an adaptation to persist in a population it must increase fitness or reproductive success.
A distinctive feature of many biological systems is their ability to adapt to persistent stimuli or disturbances that would otherwise drive them away from a desirable steady state. The resulting stasis enables organisms to function reliably while being subjected to very different external environments.

In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal).

What is adaptation in biology?
In biology, adaptation is defined a heritable behavioral, morphological, or physiological trait that has evolved through the process of natural selection, and maintains or increases the fitness of an organism under a given set of environmental conditions. This concept is central to ecology: the study of adaptation is the study of the ...
