Air pressure (inside the lungs) is lowest when lung volume is highest, so the answer is B. when you breathe in your lungs expand, which makes the air molecules spread out, therefore the pressure is lower.

Answer:

The correct answer would be option B. lowest; highest.

Explanation:

Inspiration is the process of inhaling oxygen and air into the lungs. During inhalation, the contraction of the diaphragm and the volume of lung increases in volume, this leads to decreasing in the intraalveolar air pressure so that air flows into the lungs.

Exhalation is the process of releasing air out of the lungs while breathing. During expiration, the relaxation of the diaphragm decreases the lung volume and increases the intraalveolar pressure.

Thus, the correct answer is option B.

Answer:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0)

y-int: (0, 2)

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0) ==> When y=0

y-int: (0, 2) ==> When x=0

5. A dedicated earth science student using
const2013 [10]

Answer:

(2) 988.5 mb.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.

Why do we feel pain in our hearts when we are sad
Orlov [11]

When people say words hurt is bc your feelings com from your brain and when you feel hurt or sad your brain makes the feeling physical. Like if you are depressed then your brain makes you sleep a lot so that you don't have to feel that pain during the day. Also, people can die from a broken hart bc it isn't your physical hart that is feeling everything it is actually your brain so it makes it self sabotage.
