Which property (quality) of fossils allows scientists to determine the relative ages of rock layers? A. Fossils show change over time as species evolve.
B. Fossils form from the remains of living organisms.
C. Fossils are usually found only in sedimentary rock.
D. Fossils can be analyzed to determine their exact age

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
