2) Phosphorus. Option D.
<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.

<span>substrate; repressor; inactive
In the absence of the inducible operon, the repressor operon will be bind to the gene and prevent its transcription. When the substrate present, which is inducible operon, it will bind to the repressor so the gene can be transcripted. This mechanism can be seen in lac operon of the lactose.</span>
