Explain why stars in the main sequence stage remain stable for billions of years.

• They have a constant supply of hydrogen.

• They are balanced by gravitational forces and nuclear fusion.

• They are too small to undergo changes.

• They are protected by a magnetic field.

Describe the process that leads to the formation of a neutron star.

• The collapse of a red giant.

• The explosion of a supernova.

• The fusion of hydrogen atoms.

• The cooling of a white dwarf.

Compare and contrast elliptical and spiral galaxies in terms of their structure and star formation.

• Elliptical galaxies have more star formation than spiral galaxies.

• Spiral galaxies have a defined structure with ongoing star formation, while elliptical galaxies have less structure and minimal star formation.

• Both have similar structures but differ in star formation rates.

• Elliptical galaxies are flat, while spiral galaxies are spherical.

How does the presence of dark matter influence the structure of the universe?

• It causes galaxies to spin faster than expected.

• It slows down the expansion of the universe.

• It has no effect on the universe.

• It creates visible light in the universe.
