The Latin scientific name of a species, be it an animal, plant, fungus, or bacteria, is a two-name that consists of the genus name as the first, and species name as the second. - Example, the scientific name of Tiger is Panthera tigris. - Thus,the correct option is option 2, i.e Amoeba proteus. - The first name should be the name of the Genus. - The next name should be the name of the species. - The whole name should be italicized. - Only the genus name should be capitalized,while the name of species should start with a small letter.
