Mucus coating is required for multiple functions such as protection and dealing with substances or pathogens.
Cells differentiation occurs as cells changes from a basic type to a more specialized one. Some specialized cells include:
- Muscle cells.
- Immune cells.
- Epithelial cells.
Some of these cells including epithelial cells and mucous cells produce mucus. This particular substance has many functions but the most important are:
- Protecting mucous membranes including the lining of organs such as the lungs.
- Trapping some substances, especially nocive substances to eliminate them later.
- Containing important substances the body requires.

Answer:
B. 17°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between angles and sides. Here, the relevant relation is ...
Sin = Opposite/Hypotenuse
sin(N) = PQ/PN
sin(N) = 4/14
N = arcsin(4/14) ≈ 16.6° . . . . use the inverse function to find the angle
N ≈ 17°
The ratio 21:14 when divided by 7 on each side, is the smallest ratio that has the same value as 21:14. this becomes 3:2
then multiply both sides by a few different numbers on both sides each ,
for example, 3:2 is the same as
6:4 (3:2 times 2)
9:6 (3:2 times 3)
12:8 (3:2 times 4)
15:10 (3:2 times 5) and so on
the ratio of the right number I
divided by the left on all of them is 1.5
so,
14/10 equals 1.4 (nope)
8/4 equals 2 (nope)
9/6 equals 1.5 (yay)
12/21 equals 0.57 (Lol)
So your answer is 9:6
