Answer:
<u>Allopatric speciation</u> is the gradual emergence of two or more species as a result of the geographic separation of two or more groups of animals of the same species.
Explanation:
Speciation is the gradual process by which populations evolve in different species. It is understood by allopatric speciation, that gradual speciation that occurs due to geographical isolation between biological populations of the same species. During this speciation, a population is divided by some geographical barrier, when populations are physically isolated due to geographical barriers (rivers, mountains, among others), the genetic flow between them is interrupted and over time different races will evolve that will become in different species.
The right answer is the first phase of the general adaption syndrome.
The concept of stress was introduced by Hans Selye. He describes the mechanism of the adaptation syndrome, that is to say all the modifications that allow an organism to bear the consequences of a natural or operative trauma.
In fact, it is the double-perception of a state of divergence between a demand for adaptation at a given moment and the ability to cope with it. It is an energy expenditure. It can be positive or negative.
The stress syndrome evolves in three successive stages:
*"Alarm reaction": the defense forces are mobilized
*"Resistance stage": adaptation to the stressor
*"Stage of exhaustion": inexorably reached if the stressor is sufficiently powerful and acts a long time.
