→ 
Explanation:
Electrons displacement is explained for each reaction below:
- +2 to +4 = loss of 2 more lectrons-------oxidation
- +4 throughout reaction----no exchange of electrons
- -4 to +4 = loss of 4 electrons-----oxidation
- 0 to -2 = gain of 2 electrons-----reduction
The standard plate count is used to determine the total number of bacteria present in a specified amount of milk, usually a milliliter (mL). This is used for the grading of milk. The coliform plate count is widely used to determine the total number of coliforms present in one mL of milk sample.
