Answer:
A) ozone
Explanation:
Ozone is a secondary pollutant, that is, it is not emitted directly, but formed from other air pollutants, and highly oxidizing in the troposphere (lower layer of the atmosphere). Ozone is found naturally in the stratosphere (layer located between 15 and 50 km in altitude), where it has the positive function of absorbing solar radiation, preventing most of the ultraviolet rays from reaching the Earth's surface.
The formation of tropospheric ozone occurs through complex chemical reactions that take place between nitrogen dioxide and volatile organic compounds, in the presence of solar radiation. These pollutants are emitted mainly in the burning of fossil fuels, fuel volatilization, animal husbandry and in agriculture.
Answer:
The frequency would be stable.
Explanation:
Based on the most common symptoms of cystic fibrosis, the disease only appears on adults and elderly. This feature means that the frequency of the disease would not drop or raise because they would still reproduce and pass the allele from generation to the next, maintaining the frequency stable.
