Which statement accurately describes the use of radioactive decay?

technetium-99 is used as a radioactive tracer because it remains in the body for a long time.

some types of cancer cells are killed by directing alpha rays at the tumor from outside the body.

plants utilize radioisotopes in the same way they use nonradioisotopes because they are chemically identical.

geologists and archaeologists use different dating processes to determine the age of rocks, fossils, and ancient
artifacts

Option-(C):  Plants utilize radioisotopes in the same way they use non radioisotopes because they are chemically identical.

Explanation:

Plants acts as the primary producers for creating the right the amount or level of energy for the living beings all across the ecological pyramid. As there are millions of beings that depends upon the existence of the plants for living. Now, the radioactive substance are able to generate the optimum level of energy from there body, as there atomic structure is much different in shape and size.  And thus the plants uses some of the isotopes to have a balance level of energy reservoir to carry out the different cellular processes. As the plants consumes the chemically identical radioisotopes to avoid any mutations inside the genome of the living being.Along,with which we used a term the compatibility to certain substances which then leads to know that there are certain radioisotopes (substances) which are used by the plants to cover up the cellular mechanisms.
