Answer: A.Reproductive isolation occurred through behavioral isolation.
Speciation is a process of development of new species from the previously existing species due to reproductive barriers occur among the members of the population of species. The reproductive barrier arises due to behavior and physical differences. Behavior isolation occurs when the two populations of the same species develop some differences in behavior, to attract their mates for mating, which can lead to reproductive isolation among members of same species or related species.
In the given situation, the related species of leopard frogs have developed specific courtship call, this will lead to reproductive isolation due to behavior isolation. This will help in identifying mates of the same species and this will act as a reproductive barrier among the other related species.

Low-density lipoproteins (LDLs) can contribute to the build-up of plaque that narrows blood vessels; however, LDLs are necessary because they are used to synthesize eicosanoid
<h3><u>
Explanation:</u></h3>
The article eicosanoid is practiced to include those biologically effective lipid intercessors obtained essentially from C20 fatty acids. The 'actual' eicosanoids are provided enzymatically with high stereochemical accuracy, and this is necessary for their biological purposes.
Biosynthesis of eicosanoids concerns the progress of multiple enzymes. Eicosanoids are produced largely from unesterified fatty acids, no the CoA esters, and they work in this kind, but it is frequently noticed that they may transpire and some may admittedly be incorporated while esterified to other lipids.
Answer: yes
Explanation:
because learning how the hierarchy works let’s the student understand how an ecosystem is effected if one thing was taken or destroyed. This is an important factor because this is where adaptation begins after something happens and the animals all have to learn to adapt.
Among the northern Andean countries strongly involved in the illegal coca and drug trade, Columbia is now the predominant coca producer, so the answer would be option A.
