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.
What is the characteristic that all lipids have in common? A: The common characteristic of all lipids is they are hydrophobic, so they are insoluble in polar solvents, such as water. They are, however, soluble in at least one non-polar organic solvent. The reason lipids are hydrophobic is that their molecules have long hydrocarbon chains with 16 to 18 carbon atoms. Keep Learning.
