A star forms from cloud of gas and dust called a ​ (a)   . Gravity pulls the material together forming a hot, dense region called a ​ (b)   . Once ​ (c)   occurs, a ​ (d)   is born. If the star is big enough, it will eventually end its life with a ​ (e)   creating new elements in the process.

• nebula

• protostar

• nuclear fusion

• star

• supernova

• sunspots

• gravity

Answer explanation

A star forms from a nebula, then becomes a protostar due to gravity. Nuclear fusion starts, leading to a star. If big enough, it ends as a supernova.
