Answer:

Which phrase describes carbon-14 dating?   Its B

uses the rate at which nitrogen-14 decays into carbon-14

       its B  dates the remains of organisms to determine when they died

measures the number of unstable elements in ancient volcanic rocks

determines the age of ancient fossils older than 50,000 years old

B) decays into carbon-14 dates the remains of organisms to determine when they died.

  • The three carbon isotopes are contrasted to perform radiocarbon dating. The number of protons in the nuclei of different isotopes of a given element are the same, but the number of neutrons varies.
  • This indicates that they have distinct masses despite having extremely similar chemical properties.
  • Radiocarbon dating is a universal dating method that may be used anywhere in the globe as long as there is organic material present. It can provide chronologies for regions that previously lacked calendars and is useful for dating between the last 50,000 years and roughly 400 years ago.
  • Carbon-14 degrades over time in a predictable manner. Researchers can calculate absolute dates for anything from wood to food, pollen, faeces, dead animals and humans, as well as other materials using radiocarbon dating, which enables scientists to look into the past.

Hence, correct answer is B) decays into carbon-14 dates the remains of organisms to determine when they died.
