Ascientist has a fossil that was found in a layer of rock close to earth’s surface. he believes that the fossil is around 12,000 years old. which method would best allow the scientist to confirm the actual age of the fossil? a. finding another fossil in a deeper layer of rock b. finding another fossil in the same layer of rock c. using carbon/nitrogen absolute dating d. using potassium/argon absolute dating

When it comes to determining the age of fossils there is absolute and relative dating. Relative dating is used to determine which fossil is older, while absolute dating is used when determining the age of a particular fossil. Rocks that contain radioactive elements in it, allow scientists to determine the age of fossils using the amount of radioactivity. Carbon-nitrogen absolute dating is a method for determining the age of fossils using radioactive isotopes of these elements.

The answer is: C.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
