If there is something that is making you think you may be dilated tell your doctor you would like to be checked. I had an appointment last Friday and I have been having a little bit of pressure and told my doctor and he told me just to let them know if I would like to be checked and it would be no problem.
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. Why are water molecules polar? With 8 protons in its nucleus, and oxygen atom has a much stronger attraction for electrons than does the hydrogen atom with a single proton in its nucleus. Then there is a greater probability of finding the shared electrons near the oxygen atom than near the hydrogen atom.
Thus, water molecules are actually attracted to each other and form hydrogen bonds. Water Molecule Water Molecule Hydrogen bonds are very important to living things as these bonds allow the strands of DNA to hold together, proteins to form and water to behave as it does.
