The diagram shows the general structure of a lipid, which consists of two main parts. mc006-1.jpg which part is circled? alcohol group fatty acid carboxyl group unsaturated lipid

The circle part of the structure is the CARBOXYL PART.

Generally, lipids are naturally occurring molecules and they serve as sources of high energy value in humans. Basically, lipids are synthesized from glycerol and fatty acids. The number of fatty acids attached to the glycerol determine the type of lipid that the molecule is. The glycerol is a type of alcohol and is made up of hydroxyl ions. lipid bio molecules are soluble in non polar solvent and insoluble in water.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
