Most people kill them in two or 3 years. Those that keep them well charged, and Maintain them sometimes get 8 or 10 years, but probably NOT from current productionââââ-MEXICANââââ built Interstate brand batteries, which are , let us say, not quite as good as the old ones.
Lipids ï½ Lipids ï½ Molecules made up of mostly carbon and hydrogen atoms (and some oxygen atoms too) ï½ Nonpolar covalent bonds ï½ Hydrophobic ï½ Insoluble in water ï½ Can be identified by the 2 key parts of their assembly: one glycerol backbone and 3 long carbon chains (fatty acids)â¦ ï½ Far greater than 2:1 H:O ratio.
Most of the lipids in the cell are composed of fatty acids, which have both hydrophobic and hydrophilic properties. The hydrophobic portion is composed of long chains of carbon atoms bound to hydrogen atoms. The hydrophilic portion usually contains some carbon, oxygen, and hydrogen atoms.ost of the lipids in the cell are composed of fatty acids, which have both hydrophobic and hydrophilic properties.
