During which phase of the general adaptation syndrome are organisms best able to physically cope with stress?
Flauer [41]

a. resistance

b. appraisal

c. adjustment

d. resolution

Answer:

a. resistance

Explanation:

An endocrinologist named Hans Selye first described the collection of responses of the body to stress as General Adaptation Syndrome. He describes this syndrome in 3 phases. These include:

The alarm phase: this is the initial phase where the body witnessed the stressful and the body’s energy is boosted.

The Resistance Phase: This is the phase that follows immediately after the alarm phase. Here, the body’s autonomic nervous system helps the body in trying to resist and adapt well to the stressor. This is the phase in which an organism is best able to physically cope with the stress.

The exhaustion phase: When the stress continues at this phase, the body loses its ability to cope with the stress as energy is depleted.

This means that black-eyed is the dominant trait in the species. That means if a phenotype is orange-eyed then it is homozygous recessive (bb). There will be no black-eyed since all of them are recessive.
