The first one is activating the negative feedback loop which responses to reverse the change of direction, as this keeps constant, the maintenance of homeostasis is allowed. acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large.
As the procedure is normally referred to, homeostatic equilibrium is the procedures required by a living being towards the successful regulation of its internal functions. The major purpose behind homeostasis is for practical purposes to maintain our body's internal balance or stability whether it is physical or chemical in nature.
