Arrange the following stars in order of their evolution:
a star with no nuclear reactions going on in the core, which is made primarily of carbon and oxygen.
a star of uniform composition from center to surface; it contains hydrogen but has no nuclear reactions going on in the core.
a star that is fusing hydrogen to form helium in its core.
a star that is fusing helium to carbon in the core and hydrogen to helium in a shell around the core.
a star that has no nuclear reactions going on in the core but is fusing hydrogen to form helium in a shell around the core.

1. A star of uniform composition from center to surface; it contains hydrogen but has no nuclear reactions going on in the core.

2. A star that is fusing hydrogen to form helium in its core.

3. A star that has no nuclear reactions going on in the core but is fusing hydrogen to form helium in a shell around the core.

4. A star that is fusing helium to carbon in the core and hydrogen to helium in a shell around the core.

5. A star with no nuclear reactions going on in the core, which is made primarily of carbon and oxygen.

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.
