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.

The elbow is made up of the humerus, radius and ulna so your answer is A
Answer:
People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.
