Answer:
The alveolar membrane- is where gas exchange between the blood and the atmosphere takes place. The gas molecules must diffuse across the alveolar epithelium and the capillary endothelium. ... Thus, the alveolar surface (as well as the respiratory bronchioles) have no cilia or mucus layer.
Explanation:

Number of types of bread for making sandwich = 2
Number of types of meat for making sandwich = 3
Number of types of cheese for making sandwich = 2
Then
Number of different sandwiches that can be made = 2 * 3* 2
= 12 sandwiches
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option.
Answer:
Subtract 4x4x from both sides of the equation.
y=16−4xy=16-4x
2x+3y=−22x+3y=-2
Replace all occurrences of yy in 2x+3y=−22x+3y=-2 with 16−4x16-4x.
y=16−4xy=16-4x
2x+3(16−4x)=−22x+3(16-4x)=-2
Simplify 2x+3(16−4x)2x+3(16-4x).

Replace all occurrences of xx in y=16−4xy=16-4x with 55.
y=16−4⋅5y=16-4⋅5
x=5x=5
Simplify 16−4⋅516-4⋅5.

y=−4y=-4
x=5x=5
The solution to the system of equations can be represented as a point.
(5,−4)(5,-4)
The result can be shown in multiple forms.
Point Form:
(5,−4)(5,-4)
Equation Form:
x=5,y=−4x=5,y=-4

4x+y=16,2x+3y=−24x+y=16,2x+3y=-2
