Spread spectrum. In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth.
Lipids are one of the four major groups of organic molecules; the other three being proteins, nucleic acids (DNA), and carbohydrates (sugars). Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen.
Best Answer: Because lipids are not linked together to form polymeric chains. Lipids are a very broad class of molecules. Anything that can be extracted from a cell using an organic solvent is a lipid. But when most people think of lipids, they think of fats.Fats are made when three fatty acids (long chain carboxylic acids generally made of between 14 and 18 carbon atoms) are linked to a molecule of glycerol.nything that can be extracted from a cell using an organic solvent is a lipid.
