Radiocarbon Dating Used to calculate the age of plant and animal remains While organism alive carbon-14 to carbon- 12 ratio stays same When organism dies,
It can be difficult to determine the ages of objects by sight alone. e.g. It can be difficult to tell which students in a classroom are oldest. Radioactivity.
