Question

question 8
all stars, regardless of size, eventually ___.
○ turn into black dwarfs
○ explode
○ run out of fuel and collapse
○ become black holes

Explanation:

Stars generate energy through nuclear fusion. Once the fuel for this process (usually hydrogen) runs out, they can no longer support their structure against gravitational forces and will collapse. Not all stars become black dwarfs (only low - mass stars after a very long time), not all explode (only massive stars in certain conditions), and not all become black holes (only very massive stars).

Answer:

run out of fuel and collapse
