All cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.
<h3>What is an
epithelium?</h3>
An epithelium is a specialized layer of cells that play different roles in the organism (e.g., transport of substances, digestion, etc).
Epithelia are one of the four types of tissues that form the body, which also include connective tissue, muscle tissue, and nervous tissue.
The ciliated columnar epithelium is a special class of epithelium that contain cilia that are used to move substances across their cellular surfaces.
In conclusion, all cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.

The correct answer is B.) Contraction
Answer:
it would change to 144 percent
Answer:
Ok! thank so much for letting me know!
Answer:
61 for Plate 1 ,
59 for Plate 2
Explanation:
Given that the original stock has a concentration of 6 * 10^6 infectious virus particles /mL
and it was diluted by 1:10000
New concentration = ( 6 * 10^6 ) / 10000 = 600 infectious virus particles/ mL
Also given that the virologist plates 100 mL of each sample
therefore; 0.1 mL has a count of 60.
The experimental results that he is most likely to observe in the duplicate plates will be ;
61 for (Plate 1) ,
59 for (Plate 2)
