Final answer:
The scientific name of an organism comes from its genus (C) and species, following the binomial nomenclature system introduced by Carl Linnaeus. Therefore, to answer the question, an organism's scientific name comes from its C. Genus.
Step-by-step explanation:
An organism's scientific name is derived from its genus and species. This is known as the binomial nomenclature, a system developed by Carl Linnaeus, which is universally used in the scientific community. The proper order of classification categories from most broad to the most specific is: domain, kingdom, phylum, class, order, family, genus, and species.
For example, the scientific name of the domestic dog is Canis lupus, with Canis being the genus and lupus the species. Each level of classification is known as a taxon; thus 'Canis' is the taxon at the genus level whereas 'lupus' is the taxon at the species level.
The scientific name of an organism is derived from its genus. The genus is a category in the taxonomic classification system, which is used to group similar organisms together.
The scientific name consists of the genus and the species, with the genus name capitalized and the species name in lowercase. For example, the scientific name for a dog is Canis lupus, where Canis is the genus and lupus is the species.
Therefore, to answer the question, an organism's scientific name comes from its C. Genus.
