Radioimmunoassay (RIA) is a test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood.
In 1959, biophysicist Rosalyn Yalow and physician Solomon A. Berson developed a sensitive method for measuring very small amounts of a substance in the blood called radioimmunoassay (RIA).
Radioimmunoassay (RIA) is a technique that make use of radioisotopes, usually iodine-125, as a tag or label for the detection of antigen. This technique determines the concentration of an antigen based on the competitive binding between radiolabeled and unlabeled antigen for its specific high affinity antibody.
It is very sensitive that it can measure concentrations up to 0.001 μg/ml.

Answer:
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.
Explanation:
Answer:
cause cells to shrink due to an increase in the osmolarity of extracellular fluid.
Explanation:
Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.
A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.
Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.
Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).
