Answer:
The correct answer will be option-nasal cavity.
Explanation:
The pharynx is the hollow tube which is divided into three parts: the nasopharynx, oropharynx, and hypopharynx.
The nasopharynx is the upper part of the throat present behind the nose which is 3 to 4 cm long and 2 to 3 cm wide. The nasopharynx connects the mouth to the nose and allows a person to inhale through the nose.
Thus, the option-nasal cavity is the correct answer.

Answer:
third option should be correct
Explanation:
Answer:
Polypeptide
Explanation:
Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.
In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.
