<h3>What are proteins?</h3>
Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.
According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.
Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.
Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.

Answer:
From the sea to reproduce in freshwater.
Explanation:
From fisheries, we can know about many types of fishes. Anadromous is one type of fish which migrate during their life cycle.
Anadromous fish are born in freshwater in the first stage of their lives. Then they migrate to the ocean as juveniles. This migration occurs so that they grow into adults into the sea. After becoming adults, they again migrate beck into the freshwater. They reproduce into the freshwater after migrating back into the freshwater from the sea.
So, we can say that there is two migration in the whole life cycle of anadromous fishes which is occurred so that they can reproduce.
