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.

The least reactive element in the third period is argon.
Answer:
Energy transfer will stop when both objects reach equilibrium
Explanation:
Answer:
The offspring with large, deeply colored flowers is produced from vegetative reproduction which the offspring with small, lightly colored flowers is produced from sexual reproduction.
Explanation:
Reproduction of a plant is the propagation of that plant and it occurs via the sexual or asexual means. The asexual means also called vegetative reproduction involves only one parents and the resulting offspring grows from a part of this parent. Sexual reproduction involves the union of sex cells from two parents (male and female).
In asexual or vegetative reproduction, the offsprings are genetically identical to the parent they emanate from while in sexual reproduction, the offsprings can be genetically different due to the process of recombination that occurs in gametes during their formation (meiosis). This allows for genetic variation among the offsprings.
Therefore, the offspring that resembles the parent i.e. large and deeply colored was likely produced by the vegetative or asexual means of reproduction while the offspring that exhibited a different characteristics from the parent was produced from sexual reproduction.
All are part of domain Archaea. Archaeabacteria are prokaryotic or no nucleus present and are <span>unicellular organisms. They are often characterized as having the ability to thrive in extreme conditions. Mesophiles are found in high salt content areas. Thermophiles in high temperature areas. Acidophiles in high pH areas.</span>
