Answer:

A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule

Explanation:

Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.

However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.

This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.

Tomtit [17]

Answer:

Referred pain

Explanation:

Referred pain may be defined as the pain perceived at differnet location of body other than the individual pain location.

Referred pain depends upon the intensity and duration of the pain. Refereed pain is generally generated by the potent mechanism of temporal summation. Referred pain is the condition of the body in which the uninjured body part experiences pain due to the injury of another body part.

Thus, the correct answer is option (b).
