Acid rain can be very harmful, mildly harmful, or not harmful at all. It mainly depends on the density of the rain, and how bad the current air pollution in the area is. Also, it depends on how often the area gets acid rain. The first few times an area gets acid rain, it's nearly harmless. Then, the next few it can be very dangerous, but eventually gets weaker over time. More air polluted areas are more likely to get much more harmful acid rain.
Summary: Acid rain is usually mildly harmful, mostly only harmful to infrastructures.<span />

Explanation:
because not many people count how many words they have each week.
The mRNA generated below was produced in the <em><u>nucleus </u></em>of the cell.
Messenger RNA or mRNA is a type of RNA that is an essential component of protein synthesis or gene expression. It is synthesized using the template that is the nucleotide sequence of DNA.
- The synthesis of the mRNA s called transcription
- The nucleus is the location of the production of mRNA in eukaryotic cells from linear DNA strands.
- It requires nucleotide triphosphates as substrates
- catalyzed by the enzyme RNA polymerase II.
Thus, the process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
