In a way the question has no answer. Peptide bonds don't "look like" anything, because they're smaller than wavelengths of visible light.
Structurally, they're formed when an amine reacts with a carboxylic acid. The amine group loses a hydrogen, the carboxylic acid group loses a hydroxyl ion, and the carbon and the nitrogen join. Unfortunately, it's not really feasible to draw the structure here, but any biochemistry book should provide examples.
Protein molecules look differently from one another. It really depends on the cell and what kind of protein molecule they need to perform certain functions.
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
Depends greatly on the salt or the protein. There is not one salt or one protein molecule, so you will have to be more specific.

Protein
A protein Molecule
The type of molecule that is an enzyme is a protein molecule.
Cellulase is an enzyme that break down celluse a complex organic molecule into simpler molecule like glucose and as such being an enzyme, it is also protein in nature.
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
The molecule that can bind to a receptor protein is called a ligand.
Depends greatly on the salt or the protein. There is not one salt or one protein molecule, so you will have to be more specific.
Any organic molecule contain carbon.

Protien!!! :)
it looks like cookies
it is a water channel, a protein molecule
