An occluded front is a type of weather front formed in the process of cyclogenesis when a cold front is overtaken a warm front. When this happens, the warm air is separated from the cyclone center at the Earth's surface.

An occluded front likely bring much precipitation kind of weather.

The purines are bases in the DNA. The two purines in DNA are Adenine and Guanine. These two purines forms hydrogen bonds with their complimentary pyrimidines such as Thymine and Cytosine to keep the two rails of the DNA molecule together.

Oxygen deficiency or decreased oxygen levels in the blood is a condition known as Hypoxemia.

Tubes that bifurcate from the windpipe are called Bronchi.

Land breezes are more common during winter and fall season. It occurs as it becomes night, the air on the land colls fast and air on the water surface are warmth than that and begin to rise.

Transcription is a process of production of mRNA which occurs in the nucleus of the cell. After transcription, translation which occurs in the cytoplasm.

Let p be the required number of days.

From the given data,

12 x 14 = 12 x 5 + (12+3) x p 

12 x 14 = 12[5 + 3p]

14 = 5 + 3p

3p = 9

p = 3 days.

Hence, more 3 days all of them take to complete the remaining work.

The given series 404, 415, 402, 413, 400, ? follows a pattern that,

404

404 + 11 = 415

415 - 13 = 402

402 + 11 = 413

413 - 13 = 400

400 + 11 = 411

Hence the next number in the given number series is 411.
