Answer: The answer is natural selection
Explanation:
Natural selection explains how certain desirable traits like;
- shape of the beaks of Darwin's finches: to help them feed more easily
- industrial melanism to raise a population of dark-coloured organisms to evolve from pre-existing light coloured ones in industrial areas where the surrondings are blackened with soot;
are favored over LESS DESIRABLE TRAITS, resulting in organisms that are most suited/adapted to thrive in an environment, which is evolutionary change

Explanation:
There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:
1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.
2. The stage of resistance- this occurs till the stress is removed.
3. The stage of exhaustion
