Preps the cell for mitosis
telophase
interphase
prophase
anaphase

Option B, interphase

Explanation:

During an interphase, the cell prepares itself for mitosis. There are basically three sub phases in the interphase –  

a)G1 –  

During the G1 phase, protein synthesis takes place to cater the requirement of cytosol in the cell. This phase occur just after a cell division

b)S-

It is known as the synthesis phase. A cell prepares itself for next division by making a copy of its DNA and all packaging proteins are also produced in this phase

c)G2-  

In this phase, the cell just gets ready to enter into mitosis cell division process. The cell organelles start duplicating themselves  

Hence, option B

a polymer is a chainlike molecule made up of small molecular units. these small molecular units are called monomers. monomers of polymer can be joined together either naturally or synthetically.  

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
