Put the different stages of the life cycle of an average start in the correct sequence. (1 point)

Answer 1

The correct sequence of the different stages of the life cycle of an average star is:

1. Nebula: A cloud of gas and dust in space.
2. Protostar: The beginning of a star, formed from the contraction of the nebula.
3. Main Sequence: The stage where the star is stable and fusing hydrogen into helium in its core.
4. Red Giant: A phase that occurs when the hydrogen in the core runs out, causing the outer layers of the star to expand.
5. Planetary Nebula: The outer layers of the red giant are shed, forming a glowing shell of gas and dust.
6. White Dwarf: The remaining core, composed mostly of carbon and oxygen, which slowly cools and fades away.
7. Black Dwarf: The final stage, where the white dwarf has completely cooled and no longer emits light.
