The right option is c. Nucleotide, DNA, allele, gene, chromosome

Nucleotide is the basic structural unit (monomer) of a nucleic acid such as DNA.

DNA is a polymer of nucleotides that contains genetic information of a cell. A DNA nucleotide is made up of three parts which are; a nitrogen base, a five-carbon sugar, and a phosphate group.

An allele is a possible form of a gene. Genes usually have two alleles; a recessive allele and a dominant allele.

A gene is a small part of DNA that stores information.

Chromosomes are thread-like structures, composed of protein and one molecule of DNA that carry genetic information in the form of genes.

soldier1979 [14.2K]

Answer:

<u> Option-(B): </u> If biological species are defined in terms of reproductive compatibility, the formation of a new species hinges on <u>reproductive isolation.</u>

Explanation:

There is diversity among being and we see that millions of species roam the face of land, all this happens in the tenure of centuries. While the process of evolution or creation of new species happens when a certain specie is kept inside such an environment or a very unique environment that the species is tempted to cross with another form of organism belonging to a different specie, so, this process initiates the creation of new species or organisms having a very different set of characteristics as compared to there ancestors.
