Question

Quizplus · Accepted Answer

The half-life of ¹⁴C is 5,730 years, which means that after 5,730 years, half of the initial amount of ¹⁴C will decay. Therefore, after 11,460 years, two half-lives have passed, and the initial amount of ¹⁴C would have decayed to 25% (half of half) of the initial amount. Therefore, only 25% of the original ¹⁴C will still be present in the organism's bones. So, the correct answer is D, 25%.
