alcohol
An NHR functional group would be referred to as an amine. An example of an amine: CH3CH2CH2NH2 This is 1-aminopropane.
This is the group amine.
Carboxyl
The carboxyl group. Carboxyl acts as an acid by contributing an H plus to a solution.
To know which would be the two amino functional groups the groups need to be included as well. Not seeing what group choices there are dies not allow someone to know the answer.
Lignin would fall into the functional group OH.

I learned about homologous and heterozygous structures in Biology.
The human arm would be homologous, as it is homologous to various other animals, such as a whale's fin, or a chimpanzee's arm.
the higher the polarity on a functional group, the more reactive it is. If a functional group is non-polar, it doesn't react with anything without a LOT of energy.For example: a hydrophobic functional group would avoid water at all cost, because it is non-polar, whereas water is polar. Try not to think of this as a "likes repel" sort of thing, but rather that a non-polar functional group is one that has no charge on it, and a polar group has a (+) or (-) charge. While it is true that two (+)'s will repel each other, if there is a (+) functional group, there is likely a (-) one on the other side, which would cause the molecule to flip around and bond that way.Essentially, polarity of a functional group functions as the + or - charge used to bond to the opposite charge of another molecule/functional group.
Polarity occurs when there are un-bonded electrons within the molecule. Without the alcohol functional group, the cholesterol molecule would be non-polar. However, since there is an alcohol functional group, the oxygen's extra electrons cause this molecule to be polar. This alcohol functional group allows the possiblility of linking with other molecules using an ester or hydroxyl bond.
Functional groups help to determine how the molecule reacts. For instance, if a carbon chain has a large number of methyl groups, then you would know that the molecule would be hydrophobic and found in a hydrophobic environment. On the other hand, if a carbon chain had a carboxyl group, then it would be found in a hydrophilic environment and would make the solution acidic. In addition to determine what kind of solutions they would be found in, functional groups indicate what the molecule will react with and what it will bind to.
