Detailed explanation-1: -Scientists generally refer to an organism only by its genus and species, which is its two-word scientific name, in what is called binomial nomenclature. Therefore, the scientific name of the dog is Canis lupus. The name at each level is also called a taxon. In other words, dogs are in order Carnivora.

Detailed explanation-2: -Binomial nomenclature is the formal naming system for living things that all scientists use. It gives every species a two-part scientific name. For example, a ladybug found in the United States goes by the fancy name of Harmonia axyridis. The first part of a scientific name, like Harmonia, is called the genus.

Detailed explanation-3: -Binomial nomenclature gives each species a scientific name. Scientific name consists of two parts. The first is genus name and second is species name. It is always written in italics (if typed) or underlined (handwritten).
