• organism A in Protista and organism B in Plantae

• organism A in Animalia and organism B in Fungi

• organism A in Animalia and organism B in Plantae

Which of these is demonstrated by the information below?

A student wants to use the Venn diagram below to show the characteristics of two kingdoms of organisms. The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersect.

Which of these is a characteristic that the student should list in the shaded part of the diagram?

• Heterotrophic

• Mobile

• Prokaryotic

• Multicellular

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?

• The standardized name differentiates mountain lions and pumas.

• The standardized name is less descriptive of the animal that has been observed.

• Communication with other scientists about mountain lions will be reduced.

• All scientists will be using one name for mountain lions.
