Answer:
Carobon-14 can find the age and also can find how long its been since the organism died.
Step-by-step explanation:
Carbon-14 is used to esimate the age of carbon containig substances.Carbon atoms circulate between the oceans and living organism at a rate very much faster then they decay.As a result the concentration of C-14 in all living things keep on increasing.After death organism no longer pick up C-14.By comparing the activity of a sample of skull or jaw bones,with the activity of living tissues,we can estimate how long it has been since the organism died.This process is called carbon dating.
