Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.
Answer:

-Hope this helps.
Answer:
The minimum difference is already the value of 1
Explanation:
When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.
Yes you need to call another ambulance because you need to take care of someone with a broken arm , head injury (also unconscious) you would need another ambulance to check on the pregnant woman and man with cuts and scratches.
I would say B and interesting username<span />
