A substance that reacts with certain metals to produce salts and releases hydrogen ions into water. Acids give certain dyes a reddish tint and have a sour flavor. Some body-produced acids, such as stomach acid, can support organ function. Hydrochloric acid is a kind of acid.
What is Ionization Reaction?
A neutral atom or molecule can become electrically charged atoms by obtaining or losing a free electron, which is the definition of ionisation. Ionization takes place during a chemical reaction. An atom or molecule must either lose or gain electrons in order to ionise; the electron that is gained or lost creates an ion. An anion is a negatively charged atom or molecule that has gained an electron.
The atom or molecule that gains a free electron but loses it becomes positively charged and is known as a cation. Energy is either released or gained during ionisation.

There are two sites on the antibody molecule that have a potential to bind to a non-self molecule. The Fab of an antibody is the region of the antibody that binds to an antigen. It consist of one constant and one variable domain from each heavy and light chain of the antibody. During immune reaction, an antigen-antibody reaction occurs between the antibodies made by the B cells and the antigens.
Answer:
a) positive feedback
Explanation:
positive as in increasing
