1 Answer

Answer :

a) Agglutination is defined as clumping of particles that have antigen on their surface and is brought about by antibodies.

Agglutination is a phenomenon that occurs when there are particles with antigens on their surface and antibodies that bind to those antigens. The binding of the antibodies to the antigens causes the particles to clump together, forming a visible aggregate. Agglutination can occur with a variety of particles, including cells, bacteria, and viruses, and it is a key principle in many diagnostic tests for infectious diseases.

Hemolysis, on the other hand, is the rupture of red blood cells. It can happen naturally or as a result of an external force, and it can cause the release of hemoglobin, the protein that carries oxygen in red blood cells. Hemolysis can be caused by a variety of factors such as mechanical stress, chemical damage, or bacterial infections.

Reaction is a general term that could refer to different type of biological or chemical reactions. In this context, it's not specific enough to be an answer to the question.
