The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.
That's the function of the nucleus.
The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. ... Ribosomes make proteins; therefore, the nucleolusplays a vital role in making proteins in the cell. Function of the Nucleolus. Ribosomes are made of two subunits, a large and a small
