Studying the decay of radioactive isotopes in dead organisms helps scientists to identify fossilized remains. The ratio of C-12 to C-14 in the atmosphere is 1 x 10^12. The table shows this ratio inside the body of three organisms. C12/C14 Ratio Organism A 1 x 10^12 B 2 x 10^12 C 4 x 10^12 What can most likely be concluded from the above information? Only Organism A is dead, and Organism C is older than Organism B. Only Organism A is dead, and Organism B is older than Organism C. Both Organism B and Organism C are dead, but Organism C has been dead longer than Organism B. Both Organism B and Organism C are dead, but Organism B has been dead longer than Organism C.
