Answer: Increased pressure gradient
Explanation:
The movement of gas takes place by the help of diffusion. The pressure is established in between the two different types of gases.
The movement of gas from higher concentration to lower concentration will take place when a pressure gradient is established in between them.
So, if there is an increased pressure gradient between oxygen and carbon dioxide then gaseous exchange will take place.

Answer:
Nitrogen oxide air pollution has the following impacts:
- Nitrogen oxides are respiratory irritant.
- causes photochemical smog
- Acts as ozone precursor.
Explanation:
- Oxides of nitrogen, when inhaled causes severe damage to the lungs and destroy the lung tissues causing severe respiratory problems.
- Presence of oxides of nitrogen in atmosphere creates a brown haze over the sky and results in photochemical smog.
- oxides of Nitrogen undergo decomposition in presence of sunlight resulting in formation of ozone. thus, it is a ozone precurzor.
- Ozone is very harmful when present at ground level.
