A macromolecule is a very large molecule made up of smaller units called monomers. The monomers may be the same or slightly different. Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds. Four main types of macromolecules control all activities. They are proteins, carbohydrates, nucleic acids and lipids. Their monomers are amino acids, sugars, nucleosides and glycerol and fatty acids.
The SuperCab is Ford's version of an extended cab. Instead of having four full doors, as with the crew cab, the SuperCab has a full passenger door, full driver's door and two half doors in the back.
A supercell is an organized thunderstorm that contains a very strong, rotating updraft. This rotation helps to produce severe weather events such as large hail, strong downbursts, and tornadoes. Supercell storms are usually isolated from other thunderstorms because it allows them to have more energy and moisture from miles around. These storms are rare, but always a threat to life and property.
