Explanation:
A protein purification is a series of processes that allow the isolation of a single type of protein from a complex mixture. Protein purification is vital for the characterization of the function, structure interactions of the protein of interest, for example an enzyme a cell receptor or an antibody. The initial material is generally a biological tissue or a microbial culture. There are several steps in the purification process; it can release the protein from the matrix that confines it, separate the protein and non-protein parts of the mixture, and finally separate the desired protein from all the others. This last step may be the most laborious aspect of protein purification.

The statement that describes a method by which the body prevents airborne pathogens from entering the lungs during respiration is as follows: the mucus in the nose traps microscopic particles and bacteria while nose hairs filter out larger particles.
<h3>What is the role of the lungs?</h3>
The lungs are biological organs of vertebrates that controls breathing and oxygenates the blood.
The lungs is the major breathing organ of the body and is connected to the nose through a pipe called trachea and bronchi.
However, to prevent unwanted or foreign particles in the atmosphere from entering into the lungs, the mucus in the nose helps trap the microscopic particles while the hairs in the nose blocks the passage of larger particles.

Answer:
Ventilation is the movement of a volume of gas into and out of the lungs. Respiration is the exchange of oxygen and carbon dioxide across a membrane either in the lungs or at the cellular level.
Explanation:
The expressed (coding) regions of eukaryotic genes are called EXONS.
