Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>

Complete Question:
The nurse administers erythromycin ointment (0.5%) to the eyes of a newborn and the mother asks the nurse why this is performed. Which explanation is best for the nurse to provide about neonatal eye prophylaxis?
1. Protects the newborn's eyes from possible infections acquired while hospitalized.
2. Prevents cataracts in the newborn born to a woman who is susceptible to rubella.
3. Minimizes the spread of microorganisms to the newborn from invasive procedures during labor.
4. Prevents an infection called ophthalmia neonatorum from occurring after delivery in a newborn born to a woman with an untreated gonococcal infection.
Answer:
4. Prevents an infection called ophthalmia neonatorum from occurring after delivery in a newborn born to a woman with an untreated gonococcal infection.
Explanation:
Ophthalmia Neonatorum is an eye infection that affects newborns within the first 30 days after birth. It is also known as “conjunctivitis of the newborn) and is caused by contact of the newborn’s eyes with the birth canal of a mother who has an untreated sexually-transmitted infection like Gonnorrhea.
The newborn is usually treated with an erythromycin eye ointment instilled onto the eyes.
Marquis reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds. It is composed of a mixture of formaldehyde and concentrated sulfuric acid, which is dripped onto the substance being tested.
Xylem
Explanation: Xylem carries water and nutrients upward from the roots to the leaves.
