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.

These are common questions, particularly after someone finds out their score from an IQ test. Lewis Terman (1916) developed the original notion of IQ and proposed this scale for classifying IQ scores: Over 140 - Genius or near genius. 120 - 140 - Very superior intelligence.
The average person will score around 100 on a standard IQ test. A person who registers a score of 140 or above is considered a genius.. People who get a score of under 70 are considered to be feeble-minded.. The amount of time it will take to complete an IQ test depends on the version of the test being taken.
