The isotope known as carbon 14 is radioactive and will decay into the stable form nitrogen 14. As long as an organism is alive, it ingests aic, and the level of carbon-14 in the organism remains the Same. When it dies, it no longer absorbs carbon-14 from the air, and the carbon 14 in the organism decays The half-life of carbon 14 is 5770 years. Assume an organic Samples 12,000 years old Determine how many balf-lives are in 12,000 years. Then use this answer to determine what percentage of the original amount of carbon-14 remains after 12,000 years. Round your answer as a etcentage to the nearest wole number La
