Question

Carbon dating method measures the radioactivity of C-14 and ratio of ___________ present in the organism's body
​

Answer 1

Answer:

C-14 to C-12

Explanation:

Carbon consumption of animals and plants

stops after death and since then, only the decaying process of  C-14 occurs continuously. In case of dead bodies of plants and animals, instead of remaining constant, the ratio between C-14 and C-12 changes continuously as C-12 is non-radioactive. The time passed since the death of a plant or animal can be calculated by measuring the radioactivity of C-14 and ratio of C-14 to C-12 present in their body. This is 'carbon dating' method. It is used in paleontology andanthropology for determining the age of human fossils and manuscripts. Once the age of fossil been determined by such technique, it becomes easy to deduce the information about other erstwhile organisms.
