carbon dioxides
No, monomers and polymers of aldehydes and ketones do not have hydroxyl groups attached. Aldehydes and ketones have a carbonyl group (C=O) attached to at least one carbon atom and do not have any hydroxyl groups (-OH) attached to the carbon chain.
Monomers are broken up through hydrolysis reactions. This is when the monomers break and are "capped" with a hydrogen or a hydroxyl (if not, then such molecules can do damage to the body). This process is aided by enzymes (proteins) which catalyze the reactions.
Condensation.
An amino acid.
If the macromolecule is a polymer, then yes it is made of monomers. There can be some irregular macromolecules that are not polymers and thus are not made of monomers, but they are special cases (e.g. carbon nanotubes with attached side groups).

Sugars have hydroxyl groups on most of their carbon atoms. Linkage between molecules can therefore happen using different hydroxyl groups.
Dehydration synthesis. By combining molecules' hydroxyl groups and leaving an O behind or a hydroxyl group and a hydrogen group, you bond the two molecules together and have water as a by-product.
Like with all nutrients, monomers are joined together by condensation reactions. The carboxyl group and the hydroxyl group come together and produce a water molecule. The monomers are called monosaccharides, two monomers are called disaccharides, and more than two monomers are called polysaccharides.

Glycosidic bonds are how monomers (monosaccharides) are linked together to form a polysaccharide. Like with all nutrient reactions, this is done through a condensation or dehydration reaction. The two carboxyl groups of two monomers come together. One monomer donates a hydrogen, while the other donates a hydroxyl, creating a molecule of water.

The simple one word answer is polymerization. There are a number of methods of achieving this. One method is dehydration synthesis in which for example a poly alcohol is reacted with a polyacid to form a polyester and water. Another would be addition polymerization which can be achieved by use of an intiator or even UV light.Dehydration synthesis turns monomers into polymers.Monomers are broken up through hydrolysis reactions. This is when the monomers break and are "capped" with a hydrogen or a hydroxyl (if not, then such molecules can do damage to the body). This process is aided by enzymes (proteins) which catalyze the reactions.
The monomer can be categorized into three classes. The first two classes are characterized by their respective Tg values. Soft monomers, characterized by low Tg values, include n-butyl acrylate, 2-ethyl hexyl acrylate and iso-octyl acrylate. These monomers are longer chain alkyl acrylates and exhibit low water solubility (i.e., high hydrophobicity). Hard monomers, characterized by high Tg values, include styrene, methyl methacrylate, ethyl acrylate and methyl acrylate. The third class is the functional monomer with various functional groups, such as carboxyl or hydroxyl. Examples of functional monomers are acrylic acid and hydroxyethyl acrylate,which are very water-soluble. The hydrophobicity of the hard monomer depends on the monomer structure. Methyl acrylate and ethyl acrylate, which are short-chain alkyl acrylates, have higher water solubility.
