which describes why radioisotopes can be used as tracers in studying the biological and chemical processes of plants?\nthe radioisotope is chemically identical to the nonradioisotope the plant normally uses.\nthe radioisotope is absorbed more quickly than the nonradioisotope the plant normally uses.\nthe radioisotope converts the nonradioisotope normally used by a plant into a radioisotope.\nthe radioisotope travels through the plant without participating in any chemical processes.
Answer
Brief Explanations:
Radioisotopes have the same chemical properties as non - radioactive isotopes of the same element. This allows them to participate in the same biological and chemical processes as the non - radioactive counterparts in plants, enabling them to be traced.
Answer:
The radioisotope is chemically identical to the nonradioisotope the plant normally uses.
