Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.
Explanation:
DNA is necessary for the production of proteins as well as the regulation, metabolism, and reproduction of the cell.
Proteins help repair and build your body's tissues, coordinate bodily functions, and allow metabolic reactions to take place.
Structural, storage, hormonal, enzyme, etc.
Enzymes speed up the rate of a chemical reaction to help support life.
Lipases, amylase, lactase, deoxyribonuclease, etc.
