Question

Carbon-14 is a radioactive form of carbon. Carbon-12 is the most common type of carbon. The ratio of these two atoms stays constant in living things but changes after an organism dies since carbon-14 continues to decay while the amount of carbon-12 remains the same. The half-life of carbon-14 is nearly six-thousand years. If you found a bone that had no measureable amount of carbon-14 in it, what could you conclude about the animal the bone came from? A. It died recently. B. It died less than six-thousand years ago. C. It died more than six-thousand years ago. D. Nothing, since more information is needed to answer this question.
