the thing that determines it is the type of molecules that are in the substance
The shape of the molecule is a big indicator. If the molecule looks like it has some symmetry to its shape, and its poles are directly opposite of each other, then there it`s a good bet that it`s non polar.
This question is poorly worded, however cells transer information with chemical signals. The shape of the molecule transmitting the information determines what cell it can attach to and transfer the said information.
