Astudent argues that being separated geographically is the only way for speciation to occur. why is he wrong?
speciation does not usually rely on geographic isolation.
speciation can occur from biological forces as well.
speciation can occur from variation as well.
speciation does not result from adaptive radiation.

The correct answer is option A

Speciation can be defined as the the evolutionary process by which a species gets converted into the distinct species. The evolution can be due to many reasons.

Speciation can be caused due to geographical isolation which means geography can be one of the reasons for the isolation and speciation of species.

Some other examples are behavioral isolation.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
