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.
Superpave stands for SUperior PERforming Asphalt PAVEment and was developed through a Federal government program whose goal was to relate characteristics of hot mix asphalt (HMA) to pavement performance. The result was the Superpave system for the design and analysis of asphalt mixes.he change involved a switch from the old Hveem design method to the Superpave design method. Generally, this results in a paving mix which is coarser, has less sand, and less liquid asphalt. It does  lay down differently than the old B,C or D mixes.
