Answer:
When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

Answer:
each new cell needs a DNA copy, which serves as instructions on how to function as a cell. DNA replicates before a cell divides. The replication process is semi-conservative, which means that when DNA creates a copy, half of the old strand is retained in the new strand to reduce the number of copy errors.
Explanation:
Answer:
a. the first methionine in eukaryotic translation contains a formyl group.
Explanation:
Protein synthesis begins when the initiator aminoacyl tRNA carrying the initiator amino acid joins the mRNA-small ribosomal subunit complex. Procaryotes and eucaryotes differ from each other in the identity of the first initiator amino acid. In both types of organisms, "AUG" serves as an initiation codon. However, procaryotes have formyl-methionine joined to the amino acid arm of the initiator tRNA while eucaryotic initiator tRNA carries methionine as the first amino acid to be added to the protein.
