The three correct answers regarding the relationship between nebulae and stars are:
1. **Stars form from nebulae.**
2. **Nebulae form from stars.**
3. **Stars explode to form nebulae.**
These statements reflect the life cycle of stars and how nebulae serve as the birthplace of new stars, and how the remnants of stars can create new nebulae after supernova explosions.

The correct response is:
**force of gravity**
A supernova typically occurs in two main scenarios: the gravitational collapse of a massive star at the end of its life cycle, or the sudden thermonuclear explosion of a white dwarf in a binary system. In both cases, the force of gravity is a key factor in the processes leading to a supernova.

The correct response is:
**Its edges do not have clear boundaries.**
Characterizing a nebula as diffuse means that it has a spread-out appearance without sharply defined edges, indicating that the material within the nebula is distributed over a large area.

The two correct answers for identifying a planetary nebula are:
1. **central star remnant**
2. **spherical shape**
A planetary nebula typically has a central star remnant (often a white dwarf) and exhibits a spherical shape as the outer layers of the star are ejected during the late stages of its evolution.
