what is the overall mechanism and the main stages of individual adaptation the rate of adaptive reaction and the structural cost of adaptationplease answer it in short

The overall mechanism of individual adaptation involves a process of genetic and phenotypic changes that enable an organism to better survive and reproduce in a given environment. The main stages of individual adaptation include genetic variation, natural selection, and adaptation through phenotypic plasticity.

The rate of adaptive reaction varies depending on the organism and the environment, but generally, it is faster in populations with higher genetic variation and shorter generation times.

The structural cost of adaptation refers to the energy and resources required for an organism to undergo the necessary physiological and behavioral changes for adaptation. This cost can vary depending on the degree of environmental change and the complexity of the adaptation, but it is generally higher in more extreme environments
