Correct statements about elliptical galaxies:
- They typically contain very little gas and dust.
Correct statements about spiral galaxies:
- Some have a band of stars and materials through their middle, but others do not.
- They vary in how tightly their arms are wound.
For the statement "They include the universe's largest galaxies," it is not specifically true that all elliptical galaxies are the largest. While some elliptical galaxies can indeed be very large, there are also other types of galaxies, such as giant spiral galaxies, that can be even larger.
The number "100 billion" does not seem to fit within the given context of the question, so it cannot be determined how it relates to galaxy types.
The statement "Dark matter" is not a component that makes up the bulk of all galaxies. Dark matter is a hypothetical form of matter that is thought to make up a significant portion of the universe's mass, but its exact nature and properties are not yet fully understood.
