Binary fission is the process of cell division used in most of the unicellular organisms. It is very much similar to the mitotic division in the multi-cellular organisms. In bacteria's, cells dividing by binary fission copy its DNA.

kherson [118]

Answer:

a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.

Explanation:

The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.

Vikki [24]

Answer:

Yes.

Explanation:

Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
