  • 4. 

    The correct term for a "two-part naming system" is

    • A.

      Taxonomy

    • B.

      Binomial nomenclature

    • C.

      Genus and species

    The scientific name for muskox (a very hairy buffalo-looking creature from the high Arctic) is Ovibos moschatus.  The genus is which part of the name?

    • A.

      Ovibos

    • B.

      Moschatus

    • C.

      Both

    • D.

      Neither

    Correct Answer
    A. Ovibos
    Explanation
    The scientific name for an organism consists of two parts: the genus and the species. In this case, "Ovibos" is the genus of the muskox. The genus represents a broader category that includes closely related species. "Moschatus" is the species name, which distinguishes the muskox from other species within the same genus. So, the correct answer is Ovibos, as it represents the genus in the scientific name Ovibos moschatus.

    Which of the following people gave us the classification system that we still use today?

    • A.

      Carolus Linneaus

    • B.

      Leonardo Da Vinci

    • C.

      Pliny the Elder

    • D.

    Correct Answer
    A. Carolus Linneaus
    Explanation
    Carolus Linneaus is the correct answer because he is credited with developing the classification system that is still used today, known as the Linnean system. Linneaus was a Swedish botanist and physician who introduced the binomial nomenclature, a system of naming species using two Latin words, which is still widely used in biology. His work laid the foundation for modern taxonomy and greatly contributed to the organization and categorization of the natural world.

    Rate this question:

  • 8. 

    Which part of a scientific name can be descriptive (color, where it is found, etc.)?

    • A.

      The genus

    • B.

      The species

    • C.

      They both can

    • D.

      Neither - scientists aren't supposed to do that!

    Correct Answer
    B. The species
    Explanation
    The species part of a scientific name can be descriptive because it is the second part of the binomial nomenclature system, which is used to name and classify organisms. The species name often reflects specific characteristics or traits of the organism, such as its color, habitat, or location. This descriptive aspect helps to differentiate between different species within the same genus.

    With the earliest classification system, organisms were classified into which of the following groups?

    • A.

      If they flew or not

    • B.

      If they flew or were in the water

    • C.

      If they flew or were in the water or were on the land

    Correct Answer
    D. If they flew or were in the water or were on the land (walk, run, or crawl)
    Explanation
    The earliest classification system grouped organisms based on whether they flew, were in the water, or were on land (walk, run, or crawl). This classification system categorized organisms based on their mode of transportation or locomotion, distinguishing between those that could fly, swim, or move on land. This classification was likely based on observable characteristics and behaviors of organisms, allowing for a basic categorization of different types of organisms.
