Which stages do all stars have in common in their life cycles?(1 point) Responses white dwarf white dwarf nebula nebula protostar protostar black hole

All stars have the following stages in their life cycles in common:

1. **Nebula**: This is the initial stage where gas and dust are present.
2. **Protostar**: The nebula condenses under gravity to form a protostar.
3. **Main Sequence Star**: (not listed in your options, but is a crucial stage) The star enters the main sequence phase where it spends most of its life fusing hydrogen into helium.
4. After the main sequence, stars evolve into different end stages depending on their mass, leading to types like red giants and then onto white dwarfs, neutron stars, or black holes.

From your responses, the stages that all stars have in common are **nebula** and **protostar**.
