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. Steroids include cholesterol, cortisone and sex hormones, such as estrogen, testosterone and progesterone. They have a carbon backbone that contains four fused ring-like structures.
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.
Split the difference: IQ of about 120. With a maximum IQ of 122 and a minimum IQ of 114, an IQ just under 120 sounds like a reasonable guess for Michelle Obama. Although IQ 120 is a bit below the Ivy League average, it is still higher than 99% of black America and higher than 90% of white America.
