Answer 2

Unfortunately, I am not one for science, but I can try to answer some of these -

1). A large mass of gas and dust. Stars are “born” from these.

3). Smaller stars live longer. The larger a star is, the faster it’ll burn out.

4). The phase the stars spend most of their lives in.

6). No - stars are put into groups based upon their luminosity and temperature. Also, the lives of stars take different turns.

I hope this helps a bit :)
