Air is warmed and humidified in the nasal passages. this to
ward off infection
decrease sensitivity during breathing
prevent damage to the lungs
all of the above

The correct answer is c. prevent damage to the lungs

Explanation:

There are several ways in which our lungs can be damaged. The most common one is smoking, pollution, and lack of exercise. However, we have a body which helps us to avoid that our lungs can be more damaged and this body allows the nasal passages to have warmed and humidified air to prevent damage to the lungs.

1.The graph of y > 3x − 4 has shading above a dashed line.

2.The graphs of the inequalities will intersect.

Step-by-step explanation:

Which statements are true about the graph of the system of linear inequalities? Select two options.

y > 3x – 4

y < x + 1

The graph of y > 3x − 4 has shading above a dashed line.

The graph of y < x + 1 has shading below a dashed line.

The graphs of the inequalities will intersect.

There are no solutions to the system.

The graphs of the two inequalities intersect the y-axis at (0, 1) and (0, 4).
