Answer:
secretion
Explanation:
Epithelial cells are juxtaposed, polyhedral cells with much cytoplasm, developed cytoskeleton and polarity. They are juxtaposed due to the presence of cell junctions and little extracellular matrix. The abundance of cytoplasm in this type of cell is related to the intense biochemical activity. These cells perform various metabolic processes such as synthesis and secretion.
For this reason, we can state that many types of epithelial cells perform the function of secretion.
Total magnification = objective power * eyepiece
So, m = 43 * 15 = 645
So, option B is your answer!
