Yes. A nebula is just a big gas cloud. A galaxy will contain many nebulas.

The scientific explanation of planetary nebula is to do with the materials involved in making this up. It will contain a large amount of ionised gas that emits UV light creating it's unique appearance.

No, a nebula is only a few light-years across while a galaxy is thousands of light-years across.
Because of the conservation of angular momentum.

It depends on the amount of impurities it may contain but the Density or 'specific gravity' varies between 3.175-3.184; to 3.56 if high in rare-earth elements.
no. it is not because the nebula can cause the muckis to flemmup and disolve.
None. A nebula is a cloud of gas and dust that can contain young stars, but a nebula is not a planet by any means.
