Answer: Option (D)

Explanation: In case of an occluded front, the warm front is totally replaced by the cold front, in which the warm air masses are completely vanished. And due to the relatively cold temperature of the cold front, there occurs frequent changes in the different weather forming conditions.

Whereas, in case of a cold front, the cold air masses becomes much mobile and enters the region of warm air and due to its higher density it generally remains in contact with the ground surface and also pushes the warm air to rise up. Due to this, often a variety of clouds are formed resulting thick clouds, thunderstorms and lightening.

IrinaK [193]

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.

Bile is a fluid that is produced by the liver and stored in the gallbladder, so it's not a main component of blood.
