Answer:
Carbohydrates, Nucleic acids, Proteins, and Lipids
A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1.
Nucleic acids are bio-polymers, or large bio-molecules, essential for all known forms of life.
Proteins are large bio-molecules, or macro-molecules, consisting of one or more long chains of amino acid residues.
In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others.

It's typically divided into four sub-disciplines: physical oceanography (the study of waves, currents, tides and ocean energy); geological oceanography (the study of the sediments, rocks and structure of the seafloor and coastal margins); chemical oceanography (the study of the composition and properties of seawater.
<span>C) Haloalkanes (Halons) and Chloroflurocarbons (CFS's) are chemical gases that may be carried into the stratosphere, where the ozone layer resides. These chemicals react with ozone and cause a reaction that breaks ozone down into oxygen. Depletion of the ozone layer causes an increase in the ultraviolet radiation entering the earth.</span>
