Questions and Answers

What is the purpose of binomial nomenclature?

  • To categorize organisms into broad groups.
  • To provide common names for organisms.
  • To classify organisms based on habitat.

    • In a scientific name, what does the genus represent?

  • The common name of the organism.
  • The characteristics that define a species.
  • A category containing multiple species that are closely related. (correct)
  • The specific habitat of the organism.

    • How is the species name in binomial nomenclature formatted?

  • Bold and lower-case.
  • Bold and capitalized.
