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: The plant needs a pollinator as it does not pollinates itself.
Explanation:
The plant that was found in the rain forest grow there because of the climatic conditions. There was adequate amount of rain fall and optimum temperature in the forest.
It was pollinated by the insects as rain forest has different types of organisms living in there.
When that was grown in greenhouse effect there was no growth of fruits in the plant because there was no pollinator in the green house chamber.

Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.
Membrane
A membrane is a selective barrier; it lets some items pass but prevents others from doing so. These entities could be ions, molecules, or other tiny particles. Biological and manufactured membranes are the two broad categories into which membranes can be placed. Cell membranes, which are the exterior coverings of cells or organelles that permit the passage of specific components, nuclear membranes, which enclose the cell nucleus, and tissue membranes like mucosae and serosae are all examples of biological membranes. Humans create synthetic membranes for use in laboratories and industries (such as chemical plants).
