Asked by Amber


Take a look at what we recorded on our summary table. How might what we observed and learned about atoms help us to understand how carbon atoms can help us determine the age of baby Lyuba?
Answered by Amber
Just so you know, baby lyuba was a baby wooly mammoth found mummified in almost perfect condition. I just don't understand how to find how old it would be using carbon atoms?

by using the carbon isotope ratios in once living things
... it can be determined when they died (stopped exchanging carbon)
