Answer:
The correct answer is RNA polymerase does not require a primer to add new nucleotides.
Explanation:
RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.
    RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.

B. Bicarbonate
<em>The blood brings bicarbonate to the lungs, and then it is exhaled as carbon dioxide. The kidneys also help regulate bicarbonate... it is excreted and reabsorbed by the kidneys.</em>
<em>The body's main response is to get rid of more carbonic acid and hold on to as much bicarbonate base in the kidneys as it can.</em>
 
        
             
        
        
        
I believe this would be false. Chaparral biomes can have many different types of terrains. The land in a chaparral biome can be mountainous, rocky, or flat. Chaparral biomes are generally defined by their temperature and climate. They are very hot and dry, and have mild winters and extreme summers. Hope this helps.
