Smaller stars do collapse at the end of their lives. Bigger stars die in titanic supernova explosions. The cores of the stars are crushed into neutron stars or black holes, while most of the mass of the star is blown completely away from the star into a nebula.
Billions of years later, some of that nebula material may form planets around new star systems, just as has happened to the Earth.
When a star is at the end of its lifetime its mass increases.
When a star is at the end of its lifetime its mass increases.
Massive stars become neutron stars, or black holes (depending on how much mass is left at the end of a star's lifetime).
Stars with a huge mass will consume its fuel faster. in the end it becomes a supernova and soon after (in star-time) it will implode. Depending on its mass, it might become a super-massive black hole or a little dwarf where only one teaspoon of its mass will weigh in at many tons.
More white dwarves. Most stars will become white dwarves at the end of their lifetime. On a "select few" will become black holes - the most massive stars.
False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.

They are called stars. A star is a massive, luminous ball of Plasma held together by Gravity. At the end of its lifetime, a star can also contain a proportion of Degenerate_matter
The size (diameter) of a star can change over its lifetime; sometimes within hours.What really matters is the star's MASS. The most massive stars will produce a lot of radiation, and thus use up their fuel very quickly. After that: Stars up to about 1.4 solar masses will end up as white dwarves. Above that, stars up to somewhere between 2 and 3 solar masses will end up as neutron stars. Above that, stars end up as black holes. The "mass" refers to whatever mass remains once the star uses up its fuel. For instance, a supernova explosion may remove a large part of the star's mass. Likewise, massive stars may lose a lot of mass during their lifetime, through their stellar wind.
"They" don't. The world will not end anytime soon. Not in your lifetime.
