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.

Answer:
The correct answer is - to provide a slightly cooler temperature.
Explanation:
The scrotum is a sac pf skin and superficial fascia that contains testes present outside of abdomopelvic cavity or ventral body cavity, hanging provides a slightly cooler temperature f at roots of penis.

Thus, the correct answer is : to provide a slightly cooler temperature.
Digestion of the sugar athelose in this theoretical framework is controlled by an operon that displays both positive control and negative control. Translation of the ath operon is turned on when athelose is available, and accelerated when the bacterium comes up short on glucose and must depend on athelose for vitality.
