<reasoning>

Analyze cellular abundance

Water is the most abundant molecule in living cells, making up approximately 70% of a cell's total mass. Other organic molecules like lipids, amino acids, and nucleotides are present in much smaller percentages.

Identify intermolecular forces in water

Water molecules are polar, with a partial negative charge on oxygen and partial positive charges on hydrogen. The weak electrostatic attraction between the hydrogen of one water molecule and the oxygen of another forms a hydrogen bond.
