"Which best describes the protists? Protists are early eukaryotes with very simple cells. Protists are a monophyletic kingdom of very closely related species of unicellular eukaryotes. Protists are a monophyletic kingdom of very closely related species of multicellular eukaryotes. Protists are diverse eukaryotes, typically unicellular, that do not fit into the plant, animal, or fungal kingdoms.

"It's easier to say ""cat"" than Felis catus. What is the key advantage of using the Latin binomial in this case? There are many cat species, but Felis catus specifically identifies the domestic cat and can be understood by scientists worldwide. Felis catus is more easily understood by the general public. The term cat is too specific. Felis catus is a broader category that can be used to describe any of several closely related species. It sounds more scientific to use Latin names.
