During translation, the ribosome moves in which direction relative to the ends of the mRNA?

The translation is affected by ribosomes moving along mRNA in the 5′ → 3′ direction. A set of tRNA molecules brings amino acids to the moving ribosome, their anticodons binding to codons exposed on the ribosome.

I hope this helps

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.
