The correct answer is: D. Oxygen has more protons than hydrogen and water's shared electrons are drawn to it
In water (H2O), each hydrogen atom has one positively-charged proton surrounded by a 'cloud' of one negatively-charged electron. The oxygen atom has a nucleus with eight positively-charged protons, eight uncharged neutrons and eight negatively-charged electrons. Two electron pairs of oxygen are forming covalent bonds with hydrogen, while other two pairs are lone pairs. The eight positive charges in the oxygen attract electrons strongly and this leaves the hydrogen atoms partially positively charged, and the oxygen atom partially negatively charged.

Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.
