  • Q10
    Adult mountain lions (Puma concolor) are almost 2 meters long. They have a black spot over each eye. The common names used throughout the United States for this species are listed below. Why is it best for scientists to use the name from the standardized taxonomic system?
    Question Image
    The standardized name is less descriptive of the animal that has been observed
    All scientists will be using one name for mountain lions
    Communication with other scientists about mountain lions will be reduced
    The standardized name differentiates mountain lions and pumas

  • Q15
    Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?
    In order to place organisms in different groups
    So that Latin names can be applied for a practical purpose
    In order to avoid confusion with the identification of organisms
    Because Linnaeus established the system
