Answer:
1. spheroidal component
2. elliptical galaxy
3. irregular galaxy
4. spiral galaxy
5. disk component
6. cosmology
Explanation:
1. True, the globular cluster M13 belongs to the spherical component or spheroidal component of the milky way galaxy because globular clusters are usually found in galaxies.
2. Since most elliptical galaxy lack new stars they usually have very little cool gas or dust to make.
3. An irregular galaxy is a galaxy that does not have a unique regular shape like other galaxies. Because irregular galaxies are formed when galaxies collide they are more common in the universe 10 billion years ago when the collision is said to have started.
4. Since the milky way galaxy is found in a low-density regions and having a spiral structure that extend from its center into the galactic disc it is called spiral galaxy.
5. The sun is a star, and is located about 28,000 light years from the centre of the milky way galaxy.
Like all the other stars in the milky way galaxy, it is located in the disk component of our galaxy: the milky way galaxy.
6. Indeed, Cosmology involves studying the physical universe, its structure, dynamics, origin and evolution.
This study of the dynamics of the physical universe involves investigating how did distribution of galaxies changes with time.
