Homeostasis adaptation
WebHomeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties … WebIntroduction. Adaptation, or ‘adaptive homeostasis’ is a highly conserved process, wherein cells, tissues, and whole organisms transiently activate various signalling pathways in response to short-term mild internal or external perturbations, thereby effecting transient changes in gene expression and stress resistance.
