1. 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 mountain lion, cougar, puma, and panther.
Why is it best for scientists to use the name from the standardized taxonomic system?
A) The standardized name differentiates mountain lions and pumas.
B) The standardized name is less descriptive of the animal that has been observed.
C) Communication with other scientists about mountain lions will be reduced.
D) All scientists will be using one name for mountain lions.
2. How and why do biologists use "taxonomy"?
A) Examine relationships between groups of organisms.
B) Provide consistent ways to name and categorize organisms.
C) Logical organized list of organisms that is easily referenced.
D) All of the above.
3. Arthropods are joint-legged animals. Spiders, crabs, pill bugs, centipedes, and millipedes are examples of the many types of arthropods. Which of these arthropods would be the most closest related?
A) Arthropods of the same family
B) Arthropods of the same class
C) Arthropods of the same genus
D) Arthropods of the same species
4. Recently scientists succeeded in interbreeding similar species. For example, Tigers can interbreed with leopards and leopards can interbreed with pumas. Tigers and lions can interbreed too. Based on such results, which of the following conclusions is most correct?
A) Cells of all species of cats have had the same number of chromosomes.
B) Thanks to scientific development, humans can interbreed very different animals.
C) Through the process of evolution, different animals gradually gain potentiality to interbreed with one another.
D) All different cats possibly arose from a single founder species and speciation occurred through adaptive radiation over time.
