Answer:
Biogeographic isolation causes changes in gene pools that result from populations being separated.
Explanation:
Biogeographical isolation consists in the separation of a population by a geographical barrier, giving rise to <u>subpopulations</u>.
With isolation, the subpopulations start to suffer different pressures from the environment and consequently the selected genes in one subpopulation will be different from the other subpopulation.
Due to the biogeographic isolation, the two subpopulations will be prevented from crossing and the differences between them will become more and more accentuated, and with that the <u>subspecies</u> appear.
Over time, these subspecies may become so different from each other that reproduction between them becomes impossible.
When this happens, reproductive isolation occurs and, consequently, the emergence of new species. When speciation occurs due to geographic isolation, it is called allopatric speciation.
The use of stem cells is without any objections since it can be used in therapies to help humans.
Organisms called <u>pathogens</u> live on or in the body of a host and cause some degree of harm.
<h3>What are pathogens, and where do they live?</h3>
These are the organism that lives inside or over the surface of our body and causes harm to us and they took nutrition from us.
The pathogen which lives inside may be in the form of some bacteria or virus.
The pathogen which causes harm to us by living on the surface of our body is called a parasite. they may reside in the form of some fungi, lice, etc.
<h3>Conclusion</h3>
These pathogens are very harmful to our body whether they live inside or on the surface of it.
