Answer:
 A molecule with 32 percent or more amount of Cytosine.
Explanation:
DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.
The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues. 
Thus, the answer is molecule with 32 percent or more amount of Cytosine.

Answer:
Osmosis occurs where the movement of water move from a region of high water potential to a region of low water potential. 
The water potential in blood capillaries need to be higher than the water content in intestinal so that the water will move from blood to intestine which cause diarrhea.
