The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
Our Sun is in the hydrogen fusion cycle of an average, mid-size, main sequence star. I have no idea what state YOUR Sun happens to be in.
A nebula is a cloud of gas (hydrogen) and dust in space. Nebulae are the birthplaces of stars.
Main Sequence
A nebula is an interstellar cloud of dust, hydrogen gas and plasma. It is the first stage of a star's cycle.

menstruation

hydrogen fusion

It uses up most of the hydrogen it started with.
the cell divids
Synthesis of DNA and many other cell organells take place during S-phase of cell cycle.
During evaporation liquid water is transformed in vapors (gaseous water).
During Mitosis
Our Sun is in the hydrogen fusion cycle of an average, mid-size, main sequence star. I have no idea what state YOUR Sun happens to be in.
