So, there are two factors in the denominators a y-1 and a y+2. So we will write both of those down and then take the highest power for each. That means a 2 for the y-1 and a 1 for the y+2. Here is the least common denominator for this rational expression.
â¢ Taxonomic structure is the scheme of hierarchical classification used by zoological classification experts (taxonomists) to describe living things.It customarily starts with kingdom and works its way down to species.

In biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, class, kingdom, etc. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms.here are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, the domain (proposed by Carl Woese) is now widely used as one of the fundamental ranks, although it is not mentioned in any of the nomenclature codes.
