Answer:
All living things contain carbon in some form. Carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates. Carbon's molecular structure allows it to bond in many different ways and with many different elements.
Explanation:
A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. ... The oxygen molecules are bonded or stuck together.

<span>The nervous system is the organized structure of nerve endings and cells called neurons. It runs throughout the body, and it's why we feel and respond to our circumstances, environment and life events the way we do. Anatomists classify the system structurally. It is organized and labeled as a bodily whole divided into two classified systems, one at the center of the system and the other making up its peripheral edges.</span>
The pH of solutions is an important chemical property. Oxygen is much more electronegative than hydrogen. Both shared electrons in an oxygen-to-hydrogen bond tend to spend more time with the oxygen atom than with hydrogen. Although the vast majority of water molecules remain intact in liquid water, at any given moment a few individual hydrogen atoms succumb to the pressure of the electronegative oxygen and lose their hold on both shared electrons. When this happens, the covalent bond is broken and a hydrogen ion<span> (positive charge because it lost its electron to oxygen, shorthand = H</span>+<span>) is released. The remaining part of the original water molecule is called a </span>hydroxide ion<span> (negative charge because it kept an extra electron, shorthand = OH</span>-). Although present at very low levels in solution, H+<span> and OH</span>-<span> ions can have enormous effects on the properties of a solution, especially when they are not in balance. In pure water, every hydroxide ion that forms creates a hydrogen ion, so there are equal numbers of anions and cations. If a solute is added to water, however, this balance can change.</span>
