What is the origin of the radioactive isotope carbon-14 used in radiocarbon dating?

• It is produced by the decay of uranium in the soil.

• It is formed through physical and chemical interactions when cosmic rays reach Earth's upper atmosphere.

• It is a byproduct of industrial emissions.

• It is extracted from deep-sea fossils.

What happens to carbon-14 in living organisms after they die?

• It continues to be absorbed at a constant rate.

• It begins to increase in quantity.

• It begins very slowly to change into other atoms at a predictable rate.

• It completely disappears from the organism's tissue.
