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>

Answer:
B. How the condition is treated between type 1 and type 2
Explanation:
Type 1 and type 2 are the two types of diabetes. Both are chronic and are dangerous for the human body. This diabetes affects the regulation of blood sugar and glucose in the body. Insulin is not produced in the body that suffers from type 1 diabetes. The body does not respond to insulin in type 2 diabetes. More common among the two types of diabetes is type 2 diabetes. The treatment of both diabetes is different. In type 1 diabetes, insulin injections are injected into the body.
Question options:
1. Placing a red blood cell in distilled water
2. Placing a red blood cell into an isotonic solution
3. Placing a red blood cell into a hypotonic solution
4. Placing a red blood cell into a hypertonic solution.
5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl
6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
Answer:
Crenation (shrinking):
-Placing a red blood cell into a hypertonic solution.
-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl
Hemolysis (swelling):
-Placing a red blood cell in distilled water.
-Placing a red blood cell into a hypotonic solution.
-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
No change:
-Placing a red blood cell into an isotonic solution.
Explanation:
Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.
