Answer: Option D) covalent bonds between water molecules
In water, hydrogen bonds are best described as covalent bonds between water molecules
Explanation:
The hydrogen bonds between water molecules are covalent bonds because they are formed when oxygen attract the lone electron in hydrogen, thus resulting in the formation of a partially negative charge on the oxygen atom and a partially positive charge on two hydrogen atoms
Thus, the sharing of electrons between oxygen and hydrogen atoms is responsible for the covalent bonds between water molecules

Answer:
- The formation of a peptide bond involves a dehydration reaction.
- A tripeptide contains three amino acid residues.
Explanation:
Peptide bonds are a type of covalent bonds that form between amino acid molecules. A peptide bond links two amino acids together by removing an hydrogen atom from the amine functional group (-NH2) and an hydroxyl (OH) from carboxylic functional group (-COOH) to release a water molecule. Hence, the formation of a peptide bond involves a dehydration reaction i.e loss of water.
This linking of one amino acid to another via a peptide bond forms a polypeptide and consequently a protein molecule. In other words, proteins are polymers of peptides. However, the linkage of three amino acids is called TRIPEPTIDE
