finlep [7]

Answer:

The correct answer is e. <em>Postzygotic barrier.</em>

Explanation:

Different species can not mate and produce viable, healthy and fertile descendence, due to certain mechanisms of <u>reproductive isolation</u>.

These mechanisms involve different kinds of barriers that make it difficult for two different species to produce viable and fertile progeny.

One of these is the <u>postzygotic barrier</u>, which avoids the hybrid zygote to develope to adultness. In these situations, there is a mix of chromosomes that can not happen to meet or that they lack information.

There are cases in which the embryo dies, but some times the individual can reach some more advanced develope stages.  If this is the case, in general, they can not survive because the organism is unhealthy. And if they reach adultness in good sate they can not leave descendence, as they are sterile.

Answer:

The direction the blood takes through the circulatory system is important because it makes sure that the nutrients and blood gets to every organ and vein in our body. the direction the blood flows is this. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart. so we can be the living breathing people we are today.

Do you think the offspring produced by the two processes are genetically identical to organism 1? Explain your reasoning.
zheka24 [161]
Yes. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. ... Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent
