Explanation:
Water molecules are polar, meaning they have dipole polarities. The Hydrogen end is partially positive while the Oxygen end is partially negative. This is due to the fact that oxygen has a higher atomic mass and hence attracts most of the electron cloud of the molecule towards its end.
This property of water is very important because it is able to dissolve polar molecules while non-polar molecules do not dissolve. This is an important property in the body of organisms because, for example, water helps in the folding of proteins (by interacting with polar motifs of a protein) hence ensuring the protein maintains their functional structural forms.
Water also dissolves significant polar molecules that are utilized by the body, such as glucose, and helps in their transportation within the body. Water is also significant in the diffusion of hormones used in cell signaling, e.t.c.
Water is also able to dissociate ionic compounds, such as sodium chloride, that are important in the osmotic pressure homeostasis of cells.
