Phospholipids consist of a polar molecule, a phosphate group, a glycerol unit and two fatty acids. They are found in cell membranes, which enclose the cytoplasm and other parts of a cell.

According to NDTV, Albert Einstein had an IQ of 160. Most people score between 70 and 130, or nowhere near Einsteinâs suggested IQ. The young genius has since joined Mensa, a high IQ society, and looks forward to meeting other people with interests similar to his own.
