None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous
membranes inside the nose and mouth release
moisture to air. It is estimated that the average adult evaporates 200 to
300 ml of water per day during this process. The process is very efficient: while breathing in through
nose or mouth, the mucous membranes are cooled down. During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the
lungs, thereby moisturizing the mucous membranes
Answer:
Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation.
