1. One cell for a Phagocyte is called amoeba.
2. A cell that produces antibodies is called B lymphocytes.
3. A cell which produces histamine in an allgeric response is called antigens.
4. A cell that allows the secondary response to be faster than the primary immune response is called Antigen‐specific T cells.
5. A cell which differentiates to form a plasma cell is called B cells.
6. A cell that destrosy cells which are infected with a pathogen (in cell mediated response is called cytotoxic, helper, and suppressor T cells.

The hydrogen ion concentration of a solution is indicated by its <u>pH </u>value.
Explanation:
- A measure of acidity or alkalinity of water soluble substances (pH stands for 'potential of Hydrogen'). A pH value is a number from 1 to 14, with 7 as the middle point.
- Under normal circumstances this means that the concentration of hydrogen ions in acidic solution can be taken to be equal to the concentration of the acid.
- The pH is then equal to minus the logarithm of the concentration value.
- Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
- The pH of a solution is a measure of hydrogen ion concentration, which in turn is a measure of its acidity.
- Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions. For a neutral solution, [H+] is 10−7, or pH = 7.
I believe it is A because I know Nonpoint source pollution can include excess fertilizers, herbicides and insecticides from
Agricultural lands and residential areas. I hope it is right.. please let me know
