Answer:
The function of G-Protein’s become defective and abnormal after the addition ADP-ribose to the G protein by the A sub unit. this phenomenon is called as ADP-ribosylation which result in the permanent activation of G-protein . When the G-Protein become active, the enzyme adenyl cyclase converts ATP into cAMP. Increase concentration in the cAMP blocks the transportation of sodium from the lumen into the bloodstream. the amount of Chloride and bicarbonate also increases. Due to the continuous increase of the ions, water moves into by osmosis from the bloodstream and cholera occurs.

Answer:
It is quite simple.
Lets start from the markings above the topic "external temperature."
3 lines after 20 C is 23 C. As you can see, both of them (animal 1 and animal 2 wave drawing on the graph) meet at that point. So thats why Option D is correct
Answer:
The mRNA transcript that is produced in the nucleus is in immature form, it had to get matured, and then its capping and tailing is done. 5' cap is added and a poly A tail is added at 3' end of this mRNA. This helps it to get matured. moreover for its maturation the non-coding regions (introns) are removed and exons are packed up again to form a mature mRNA.
This mature mRNA then proceeds to its way to the ribosomes for translation of proteins.
