Answer:
the amount of pollutants in the air is unhealthy
Explanation:
AQI or Air Quality Index assesses the air quality. It indicates how clean or unhealthy the air is and its effects. It is calculated by measuring the concentration of major air pollutants across many locations in the country. The air quality is divided into six categories:
An AQI of 201 means that the air quality is very unhealthy. Everyone is susceptible to health hazards in this air quality.

Sexual reproduction requires cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction. Thus, the correct option is D.
Sexual reproduction involves the production of new organisms through the combination of genetic information of two individuals which are of different sexes. In most of the species, the genetic information is being carried on by the chromosomes in the nucleus of reproductive cells which are known as germ cells or gametes, which then undergo fertilization and fuse to form a diploid zygote.
Gametes are produced through meiosis because these are haploid. Thus, sexual reproduction required cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction.
Therefore, the correct option is D.
