Potable water can be defined as the water that can used for drinking purpose and it should not harm the body in longer terms.
The potable water is high quality water which lacks pathogen that causes contamination.

The repeating stages a cell experiences, including cell division, compose the cell cycle.
Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.
Interphase can be subdivided into:
• G1 phase characterized by the growth of the cell
• S where DNA replication occur
• G2 phase final preparation for mitosis.
Mitotic or M phase consists of:
• Prophase-condensation of chromosomes and mitotic spindle formation
• Metaphase-alignment of the chromosomes
• Anaphase- Sister chromatids are pulled apart by the mitotic spindle
• Telophase-each pole of the cell contain full set of chromosomes.
Two new cells are formed after cytokinesis.
