Question

As a star begins to die, it runs out of hydrogen and starts to fuse into helium

True

B) False

​

Answer 1

Answer:

As the protostar gains mass, its core gets hotter and more dense. At some point, it will be hot enough and dense enough for hydrogen to start fusing into helium. ... Eventually the core of the star runs out of hydrogen. When that happens, the star can no longer hold up against gravity.

it is true

Answer 2

True.

When the star runs out of hydrogen, it can no longer hold up against gravity. Its inner layers start to collapse, which squishes the core, increasing the pressure and temperature in the core of the star.
