Question

A researcher discovers a fossil of what appears to be one of the oldest-known multicellular organisms. The researcher could estimate the age of this fossil based on __________.

Answer 1

The researcher could estimate the age of the fossil based on relative dating techniques.

Step-by-step explanation:

The researcher could estimate the age of the fossil based on relative dating techniques. Relative dating involves comparing the age of the fossil to the ages of other fossils or rock layers to determine its relative position in the fossil record. By examining the rock layers and the fossils found within them, scientists can determine the order in which the organisms lived and estimate the age of the fossil based on the known ages of other fossils.

Answer 2

A researcher discovers a fossil of what appears to be one of the oldest-known multicellular organisms. The researcher could estimate the age of this fossil based on the amount of uranium-238 in volcanic layers surrounding the fossil.
