Can a tropical cyclone originate over a hot desert

 Tropical cyclones can only form over water. There is not enough hydrologic energy over a desert to begin the cyclonic action. 

No, tropical cyclones can only form over water.

The reason why this is is because the warm water helps circulate enough energy to create a tropical cyclone, and there isn't enough water in a desert to do so.

The right matches are

interphase  : the DNA replicates

mitosis  : the nucleus divides

cytokinesis : the cytoplasm divides

The cell cycle comprises two major stages interphase and mitosis:

A. The interphase: is the longest period of the cycle, it corresponds to the period between the end of one division and the beginning of the next. It is divided into G1 phase, S (DNA replication) and G2 phase.

B. Phase M: mitosis / meiosis: where there is division of the cell (nucleus + cytoplasm).
