evolution quick check
use the diagram to answer the question.
diagram of star evolution
which of these can a star become at the end of its evolution? choose the three correct answers.
(2 points)
□ a white dwarf
□ a black hole
□ a brown dwarf
□ a neutron star
□ a supernova

Explanation:

1. A white dwarf is the final evolutionary stage for low-to-medium mass stars (like our Sun), shown in the top sequence of the diagram.
2. A black hole is the final stage for the most massive stars, forming after a supernova as depicted in the bottom sequence.
3. A neutron star is another final stage for massive stars, forming from a supernova explosion as shown in the diagram.

A brown dwarf is not a true star's final state (it's a failed star), and a supernova is an explosive event that leads to final stellar states, not a final state itself.

Answer:

a. a white dwarf
b. a black hole
d. a neutron star
