Question

section four: understanding the main ideas - high mass stars identify each stage of the life cycle by putting the letter of the picture in front of the star. black hole supernova protostar gravity causes this to condense into a protostar main sequence star when a star begins to run out of fuel and grows larger neutron star

Explanation:

High - mass star life cycle: Dust (A) condenses into a protostar (B) due to gravity. The protostar evolves into a main - sequence star (D). When the star runs out of fuel, it grows larger and then undergoes a supernova explosion (E). Depending on the mass, it can form a neutron star (G) or a black hole (F).

Answer:

Black hole: F
Supernova: E
Protostar: B
Gravity causes this to condense into a protostar: A
Main sequence star: D
When a star begins to run out of fuel and grows larger: D (as it starts to leave the main - sequence phase)
Neutron star: G
