When a star explodes as a supernova, it has finished it's main sequence, is in maturity and when it finally explodes it's in the stellar remnants stage.
A white dwarf star is capable of turning into a supernova if the fusion action is reignited. It can also happen when a star starts to collapse.
The terminal stage - the star is literally torn apart, leaving behind a dense stellar remnant.
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
sporophytic stage and reduction in the gametophytic stage.
A white dwarf is a star that is dying and is in its final evolutionary stage.
No one knows for sure, since there is not enough information to figure it out. After a supernova, the star will either turn into a black hole, a neutron star, or a pulsar. But, there is no scientific evidence that proves which one the star will turn into after a supernova.
It varies, depending on the stage of the star's development.
Supernova
yes, it is the stage where a star dies and turns into a blackhole
Lickatonge does not have and evolutionary stage.
Our sun is not massive enough to supernova. Our sun will die in a different manner, but certainly not in 2012. The process of our sun's death will be very slow. Right now, the sun is what they call a "main sequence" star and is in the most stable stage of it's life and will be for quite some time. See related question.

You need to specify a time period for the question to be answered. Synapsids, therapsids, and cynodonts could all be called the early ancestors of mammals, but each at a different stage in the evolutionary history of mammals.

It is a supergiant.(the late stage in the life cycle of a massive starin which the core heats up, heavy elements formedby fusion, and expands; it can eventually explodeto what scientist call a supernova.)-Missy K

No, It does not. it is a one stage evolutionary family. There where arguments when the first images of the shellos and its evolved form that they where gonna be evolutionary relatives of lapras but as that has been proven false, there is no known evolutionary chain for lapras
No one can be sure.However, it is hypothesised that when one of the first population III stars exploded as a supernova it created a massive black hole. This "hole" had enough gravitational influence, to attract enough material to form the first stages of a galaxy.
