Answer:
Carbon-14 in photosynthesis and Florbetapir (18F) in PIB of Alzheimer's disease.
Explanation:
These radioactive isotopes known as the biological spies as they tell or mark the presence or activity of a particular atom to the scientists in living beings.
For instance,
1. the process of photosynthesis can be understood by observing the radioactive isotope Carbon-14 from taking the carbon dioxide to the generation of glucose molecule by molecule process.
2. A protein that is deposited in people with Alzheimer's disease, called beta-amyloid. It is bind with another protein known as PIB, which contains Florbetapir (18F) a radioactive isotope. It gives an idea about the location of PIB and deposits in amyloid to try to eliminate the protein deposits and check the effect of medication.

The normal cell characteristic which is represented by the
production of insulin in the beta cells of the pancreas is performance of a
differentiated function.
<span>Insulin is produced by beta cells of
the pancreas for storing and disposing of glucose in various parts of the
body. Although gene for insulin production is present in all cells but it is expressed
only in the beta cells and this activity is a differentiated function of the
beta cells of pancreas only. </span>
