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.
SUPERCELLS. Supercells are storms --- usually, but not necessarily, thunderstorms --- that contain updrafts that rotate about a vertical axis. This rotation is derived from shear in the environmental wind field (that is, a change in wind direction and / or speed with height) surrounding the storm as it begins to grow.Supercells often produce damaging wind, large hail, and tornadoes, and most strong to violent tornadoes are associated with supercells.solated supercells (a) often appear as roughly circular or kidney-shaped blobs, with a point or hook-shaped appendage on the rear side of the echo, relative to its direction of motion. (FFD and RFD refer to the storm's front flank and rear flank downdrafts, respectively).
