Which is a <span>post-zygotic barrier to reproduction. </span><span>The postzygotic reproductive barrier is a component that lessens the feasibility or regenerative limit of half-breed posterity. Half-breed zygote variation from the norm is a sort of postzygotic hindrance in which cross breed zygotes neglect to develop regularly.</span>

A microscopic organism, especially a bacterium, virus, or fungus, most of which are not harmful unless they are a pathogen are microorganisms.
<h3>What are
microscopic organisms?</h3>
Microorganisms are microscopic organisms composed of one or a few cells, which may be harmful to human health when produce infections such as certain pathogenic bacteria.
In conclusion, a microscopic organism, especially a bacterium, virus, or fungus, most of which are not harmful unless they are a pathogen are microorganisms.

Answer:
with radiators that release electromagnetic radiation into space.
Explanation:
Spacecraft use radiators that release electromagnetic radiation into space to get rid of excess heat.
Since outer space is a near perfect vacuum, this means that many of the common ways that heat is expelled on Earth do not work in space. Since spacecraft do not touch any other objects in space, they cannot lose heat through conduction. Since there is no air, they cannot lose heat through convection either. Instead, spacecraft use specially designed radiators, which emit excess heat as electromagnetic radiation—infrared light.
We know that each parent must give one trait to a child. If that is the case, then the women has a probability of giving either an A or a B gene (since she is heterozygous AB). In order to have an A child, the child must have a genotype of either Ai (heterozygous A), or a AA (homozygous A). Since we know that the mother gave an A gene, we are now only looking for either an 'i' (recessive: stands for blood type O), or an A. Since the choices shows the phenotypes of the possible father, then their genotype could be homozygous or heterozygous (since the phenotype does not show whether an organism has a recessive gene if it's heterozygous). If that is the case, then all of them could be the father of the child.
Proof:
for letter A: mother Ai or AA x father AA or Ai = possible offspring are: AA, Ai, or ii
B) mother Ai or AA x father Bi = AB, Ai, Bi, ii
C) mother Ai or AA x father ii = Ai, ii
D) mother Ai or AA x father AB = AA, AB, Ai, B
All of them have the probability of having an A child.
