Question

consider the image of a fossil below
image of a fish fossil
how is half - life most likely used with respect to this fossil?
○ to find the mass of the fossil
○ to find the age of the fossil
○ to determine the species shown by the fossil
○ to determine if radiation is being emitted from the fossil

Explanation:

Half - life in the context of fossils is related to radiometric dating. Radiometric dating uses the half - life of radioactive isotopes to calculate the age of rocks and fossils. Finding the mass of a fossil does not involve half - life. Determining the species of a fossil is done through morphological analysis, not half - life. And half - life is not used to check if a fossil emits radiation (fossils usually don't emit significant radiation on their own in a way related to half - life for this purpose). So half - life is used to find the age of the fossil.

Answer:

to find the age of the fossil
