Supernovae are classified as Type I or Type II depending upon the shape of their radioactive decay of the unstable heavy elements produced in the explosion.

What is the difference between Type I and Type II supernovae?
supernovae are classified by the lines in their spectra (which indicate which elements are present). type I supernovae have no hydrogen lines, having been caused by the explosion of a star with no hydrogen envelope. type II supernovae have hydrogen lines, indicating that the exploding progenitor star had retained a significant amount of its hydrogen before its supernova. type I supernovae are further classified based on the presence of silicon lines, which are present in type Ia supernovae but not types Ib and Ic.
Why does a type Ia supernova make a better indicator of distance than a type II supernova?
Type Ia supernovae [See Link] follow a characteristic light curve. This luminosity is generated by the radioactive decay of certain elements. The peak luminosity of the light curve was believed to be consistent across Type Ia supernovae as having a maximum absolute magnitude of about -19.3. This would allow them to be used as a secondary "standard candle" [See Link] to measure the distance to their host galaxies
What are shocks from supernovae?
Shocks from supernovae are the explosions of massive stars.

Black holes form from the remains of stars that?
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
Almost all the Elements on Earth were produced in Supernovae?
true
Lung surfactant is produced by?
type II alveolar cells
What type of stars end their life in supernovae?
Massive Stars.

What occurs in the body with type II diabetes?
In Type II diabetes, the pancreas may produce enough insulin, however, cells have become resistant to the insulin produced and it may not work as effectively

Shocks from supernovae are the explosions of massive stars.
Is supernovae and supernova the same thing?
"Supernovae" is a plural form of "supernova"
