Which of the following is characteristic of antibodies? Group of answer choices composed of heavy and light polypeptide chains three binding sites per antibody monomer incapable of being transferred from one person to another carbohydrate structure

Composed of heavy and light polypeptide chains.

Explanation:

Antibodies are generated by the immune system mostly by the plasma cells in acknowledgment of the existence of any foreign substance, known as an antigen via the fragment antigen-binding (Fab) variable region.

Antibodies are Y-shaped in a structure that contains 4 polypeptides 2 heavy chains and 2 light chains. This structure of antibody helps to reach their dual functions one is antigen binding and another is biological activity mediation.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
