- Assuming that the global amount of radiocarbon is constant, decaying Carbon-14 is repeatedly restored in organisms while they are alive. However, when an organism dies, the amount of Carbon-14 begins to decrease as it decays to Nitrogen-14. A peat bed sample is found to have 6% of Carbon-14 remaining from a specific type of bivalve shells. How old is the peat bed?Gg.116.Can you please label all function groups in this drug. Is this drug considered an isotope? what make it an isotope?
