98. all of the following are true of water except a) neighboring molecules are held together by hydrogen bonds. b) it is less dense as a solid than as a liquid. c) it is a polarized molecule, where the oxygen is slightly positive and the hydrogens are slightly negative. d) it is the basis for all life as we know it. e) it can dissolve molecules with electrical charges.

C) it is a polarized molecule, where the oxygen is slightly positive and the hydrogens are slightly negative.

Explanation:

The water molecule is polarized, but the oxygen atom is slightly negative and the hydrogens are slightly positive.

Electronegativity is a property that measures how much an atom will tend to attract electrons towards itself. Because electrons are negatively charged, the more electronegative an atom is, the more negative its partial charge will be.

Oxygen is much more electronegative than hydrogen, and thus it will attract the electrons in the molecule, keeping them away from the hydrogens.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

b is the correct answer
