Answer 1

here is your answer mate
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet.
The adoption by biologists of a system of strictly binomial nomenclature is due to Swedish botanist and physician Carl von Linné, more commonly known by his Latinized name Carl Linnaeus (1707–1778).
