Which of the following could result in speciation from biogeographic isolation? the isolation of two populations of the same species the isolation of two individuals of the same species the isolation of two populations of different species the isolation of two individuals of different species

the isolation of two populations of the same species

Biogeographic isolation refers to the separation of the members of the same species due to geographical and biological barriers. Such members are incapable of inbreeding with the separated members. These separated members evolve to become a distinct species. The process is known as speciation.

According to the above information, the isolation of two populations of the same species could result in speciation from biogeographic isolation.

The isolation of two populations of the same species could result in speciation from biogeographic isolation.

Further Explanation:

Evolution results in changes in phenotypic traits that are transmitted from one generation to another. Mutation in genes causes a heritable change that passes onto the offspring. The transmission of that particular change from one generation to another will result in evolution.

Speciation helps in the preservation of different species during the evolution process. In this, a single evolutionary lineage is split into numerous genetically different lineages. A speciation event would occur over a while. Geographical isolation or biological forces separates different member of the same species. The group consists of animals that can easily produce offspring and can grow. By this, we study the ecosystem and distribution of species in the geographic area. The isolation of more than one individual population of the identical species could be a result of the speciation of biogeographically isolation.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
