Which of the following features of a human skeleton can be determined by carbon-dating?

Assessment: WAEC SSCE - Chemistry - 2001 (Objective) Subject: Chemistry

Question 1 Report

Which of the following features of a human skeleton can be determined by carbon-dating?
Answer Details
Carbon dating is a method used to determine the age of organic materials, such as bones and teeth. This method is based on the fact that carbon-14, a radioactive isotope of carbon, decays at a known rate over time. As living organisms take in carbon-14 during their lifetime, the amount of carbon-14 in their bones and teeth can be used to determine the approximate age of the sample. Therefore, of the options given, only the age of a human skeleton can be determined by carbon-dating. The other features such as height, mass, and race cannot be determined by carbon-dating.
