Question

ch. 4 quiz 2
a student models the life cycle of a star and includes the following stages:
nebula → protostar → main sequence → red giant → white dwarf
what type of star is being modeled?
○ a brown dwarf
○ a low - mass star
○ a high - mass star
○ a neutron star

Explanation:

The life - cycle stages given (Nebula → Protostar → Main Sequence → Red Giant → White Dwarf) are characteristic of a low - mass star. High - mass stars have a different final stage (e.g., supernova and neutron star or black hole). Brown dwarfs are not stars in the traditional sense as they do not undergo full hydrogen fusion.

Answer:

A low - mass star
