Natural Selection: Mastery Test
Finger [1]

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.

SIZIF [17.4K]

One factor that would limit the settlement on top of living organisms is the panels hang vertically from the side of a dock.

The factors that affect settlements can explain how an organism adapts to its environment. There can be numerous factors based on the situations that can limit the settlement of an organism in its new environment. Competition, predation, disturbances, resources, etc can affect the establishment of a species in an area.

A set of panels hanging vertically can hinder the settlement on top of living organisms. Many organisms are known to survive in the harsh stormy seas and many are known to live in places where freshwater and ocean surface water mix (estuaries). But if the place where the animal such as crabs and snails have to reach is hung vertically it might be difficult for them to establish themselves as it will be harder for them to reach and hang on to the panels.

What factors influence gene flow between populations? 1. Differences in animal behavior and life history strategies can form eff
Whitepunk [10]

Answer:

All these factors affect gene flow:

1. Differences in animal behavior and life history strategies can form effective barriers to gene flow.

2. The home range size of the specie can also serve as a barrier to gene flow.

Explanation:

Firstly, gene flow is the transfer of genetic traits from one population to another. It is an important process for transferring genetic variations from one population to another.

There are several barriers or factors that limit or increase this gene flow.

Gene flow can be affected by mobility or rate of dispersal. It is expected to be lower in species with low mobility which is the movement from one place to another or low dispersal and vice versa. So a population with a shorter home range size can't effective aid gene flow as they interact only with individuals of the same population and vice versa.

Gene flow barrier could be by physical barriers which is the isolation of a geographical location preventing them from exchanging genetic materials with the same species of the sane population.

This type of physical barrier is usually but not always natural.

Barrier to gene flow could be reproductive preventing transfer of genectic materials due to differences in mating period, season of birth and so on.

Another barrier could be difrerneces in customs, ethnicity, religion and clans.

All these factors affect gene flow but the 3rd and 4th option are not totally true as barriers to gene flow are not totally physical geographical barriers and not totally anatomical differences but also soil preference and other factors.

Thanks.

Which of the following explains why arteries have thicker walls than veins?
Liula [17]

Answer:

c. because arteries carry high pressure blood from the heart

Explanation:

Arteries carry the oxygenated blood that is pumped directly from the left ventricle of the heart. Since they receive blood from the heart, the blood pressure is higher in arteries than veins. To withstand the higher pressure of blood pumped by heart, arteries have thicker walls than the walls of veins.
