Examine the general structure of a molecule.

which functional groups are in this molecule?
an alkyl halide and an alcohol
a carboxylic acid and an amine
an amine and an ester
an aldehyde and a carboxylic acid

a carboxylic acid and an amine

Explanation:

A functional group is an atom or group of atoms inside a molecule that has comparable chemical properties anytime it appears in numerous compounds. When other parts of the molecule are not similar, some functional groups react in certain manners.

Carboxylic acid is a carbonyl-containing functional group, with carbon atom bonded to an hydroxyl group on one side and on the other side is either a carbon or hydrogen atom.  

An amine group is composed of a nitrogen atom bonded to a combination of carbon and hydrogen atoms.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
