Answer:
The correct answer for: A fossil formed 11,400 years ago. Which percentage of the original amount of carbon-14 remains in the fossil? Is: 25%
Step-by-step explanation:
First of all, let's explain something. Carbon-14 is a radioactive isotope present in carbon. It is used to determine the age of a certain object and it was brought to the field of dating age at the University of Chicago by Willard Libby and colleagues. However, it has a proven dating of 60 thousand years old, nevertheless very weak in the percentage of the presence of carbon-14. So the presence of it and its radiation are used to determine the age of a certain organic object.
