Answers
Answer:
By counting the carbon.
Explanation:
In the case of carbon-14, a radioactive isotope found in Earth’s atmosphere, that’s great news for archaeologists. Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and humans.The less radioactivity a carbon-14 isotope emits, the older it is. And since animals and plants stop absorbing carbon-14 when they begin to decay, the radioactivity of the carbon-14 that's left behind reveals their age.
Answer:
What are the chemicals being used for preserving mummies?
Natron, a disinfectant and desiccating agent, was the main ingredient used in the mummification process. A compound of sodium carbonate and sodium bicarbonate (salt and baking soda), natron essentially dried out the corpse.
