Answer:

Radiocarbon dating

Explanation:

Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14. Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.

One important factor cell design for exchanging materials efficiently is to have a relatively large surface area compared to the volume of the cell. An intestinal epithelial cell, for example. Instead of being a large round blob, it is long and stretched out to have a large surface area where absorption and excretion can occur. I hope this helps.</span>
