MAPK/ERK pathway. The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell.
Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain performance across a range of environmental conditions.
the adaptation of organisms to new conditions of existence. Although acclimatization literally means adaptation to the climate, the term has long been used to designate adaptation of the organism not, only to new climatic conditions but also to soil conditions and new biocenoses.Acclimatization can occur in either of two ways: (1) By changing the metabolism of organisms.uccess in acclimatization depends on the selection of subjects and the length of time over which acclimatization is carried out. Natural selection of those individuals most completely adapted to unusual conditions of existence takes place in the new environment.
