How are the reproductive cycles of a fungus and a pteridophyte similar?

 Likewise in pteridophytes, species also produces haploid spores through haploid stage. In diploid stage the two spores fuse together to form a prothallus which is a diploid stage. Hence, the similarity in the reproductive cycle of fungus and a pteridophyte is that both organisms produce haploid spores and exhibit diploid and haploid stages.

Explanation:

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
