Whereas bacterial cells typically possess only one type of rna polymerase, most eukaryotic cells possess distinct types of rna polymerase. 2 12 4 7 3

The correct answer will be option- three RNA polymerase

Explanation:

The RNA polymerase is the enzyme which helps the process of formation of RNA from DNA during transcription.

Prokaryotes possess only one type of RNA polymerase which form all type of RNA whereas the eukaryotes possess three types of RNA called RNA polymerase I RNA, polymerase II and RNA polymerase III.

These RNA polymerases catalyse the synthesis of different RNA in eukaryotes as RNA polymerase I help in the synthesis of rRNA, RNA polymerase II in miRNA, mRNA, snoRNA and  RNA polymerase III in 5S rRNA and tRNA.

Thus, three RNA polymerase is the correct answer.

c.more precipitation,but only when emission levels.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
