Molecules in all organisms are composed in part of radioactive carbon-14. Which statement best explains the presence of carbon-14 in organisms?

AThe radioactive isotope reacts in the same way as stable isotopes in the nuclear reactions in the body.
BThe radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
CThe radioactive isotope reacts faster than stable isotopes in the nuclear reactions in the body.
DThe radioactive isotope reacts faster than stable isotopes in the chemical reactions in the body.

I think the correct answer from the choices listed above would be option B. The statement that best describes the presence of carbon-14 in organisms would be that radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body. This seems to be the most suitable answer since the other choices suggest that there are nuclear reactions in our system which is very far from the truth.

The statement that best explains the presence of carbon-14 in organisms is that the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body. That is option B.

What is radioactive carbon-14?

Radioactive carbon-14 is a type of radioactive element that is present in the air which is assimilated in small quantities into the body during metabolism( chemical reaction of the body).

The radioactive carbon-14. can be used in a process called carbon dating because it reacts the same way as stable isotopes in their chemical reactions in the body.
