What is a bond dipole?

A bond dipole is when one atom in a bond has a greater electronegativity than the other atom in the bond. Therefore it has a greater pull on the electrons in the bond causing a charge separation. As a result that atom would appear to be slightly negative as the electrons are closer to it and the other would appear slightly positive as the electrons are farther away. As a result there is a charge separation and therefore a dipole.

It changes food into energy that the organism can use.

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.
