Answer: The answer is C
Explanation:
Antibodies or otherwise called Immunoglobulin are special protein that are produced by certain lymphocytes which produces antibodies which can affect the invading bacteria or other foreign bodies called the antigens or other toxins in a number of ways . Certain antibodies known as agglutinins make bacteria harmless by causing them to clump together. The lysins dissolve the outer coats of bacteria, the antitoxin neutralize the toxin of bacteria while precipitins precipitate the toxin as insoluble and therefore , convert them to a harmless compound. Antibodies are always produced by the immune system.
The answer to this question is A
The correct solution for this is explained the first option. Since water has an equivalent amount or number of H ions and OH ions, pure water itself is not slightly acidic nor basic. This equality of ions, causes the pH of water to be around the mid point of the pH scale which goes from 0 - 14, and thus is 7. This is a neutral pH.
This would be animalia (animal cells)!
