<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.

I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
The above statement is true.
Heme iron is found only in meat, poultry, seafood, and fish, so heme iron is the type of iron that comes from animal proteins in our diet. While the non-heme iron, by contrast, is found in plant based foods like grains, beans, vegetables, fruits, nuts, and seeds. However, it is also found in animal products such as eggs or milk/dairy and it also comprises more than half the iron contained in animal meat.
