Answer:

Genetic diversity in a small population, with a high level of genetic drift and with very little migration will decrease because existing alleles will be lost and few new alleles will be introduced over time (option A).

Explanation:

Evolution - linked to the natural selection and perpetuation of a species - depends, in large part, on three fundamental factors to make it happen:

  • Mutations .
  • Genetic drifts.
  • Migrations.

In small and isolated populations, very little genetic variation, high levels of genetic drift and very few mutations can be observed, which could lead to some alleles being lost and the species may become extinct.

Genetic drift (GD) is an important factor in terms of natural selection, as it is the result of allelic variations that occur from one generation to another. In large populations, GD is low, given the cross between different individuals is greater. A characteristic of GD in small populations is that their levels are very high, and this leads to the eventual loss of alleles.

In this small population, without the possibility of migration -few new alelles will be introduced- genetic variation will decrease, due the genetic flow is low, reducing reproductive fitness and weakening the population's resistance to environmental changes, which could result in the long-term extinction of the species.

alexandr402 [8]

The correct answer is diarrhea.

Diarrhea refers to an enhancement in the intensity of bowel movements, an upsurge in the looseness of stool. It is caused due to increased discharge of fluid into the intestine, rapid passage of stool via the intestine, or diminished absorption of fluid from the intestine.

The common bacterial causes of diarrhea include Salmonella, Campylobacter, E.coli, and Shigella.

Lana71 [14]
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
