Question

which statement is true about the galaxy? this type of galaxy contains little to no gas. this type of galaxy contains earth and the solar system. this type of galaxy has a high percentage of young stars. this type of galaxy is thicker near the center than near the outer edge.

Explanation:

To determine the true statement about galaxies, we analyze each option:

1. "This type of galaxy contains little to no gas" - Elliptical galaxies have little gas, which is a known characteristic.
2. "This type of galaxy contains Earth and the solar system" - Galaxies are vast; the solar system is in the Milky Way galaxy, but a galaxy doesn't "contain" Earth in the sense of a galaxy type definition (this is incorrect as a general galaxy - type statement).
3. "This type of galaxy has a high percentage of young stars" - Elliptical galaxies have old stars; spiral galaxies have more young stars, so this is incorrect for elliptical (if we assume the context of common galaxy types).
4. "This type of galaxy is thicker near the center than near the outer edge" - Spiral galaxies have a thin disk, and the bulge (center) is more concentrated but not "thicker" in the way described (elliptical galaxies are more spherical, so this statement is incorrect for typical galaxy types).

So the first statement is correct as elliptical galaxies are known to have little to no gas for new star formation.

Answer:

This type of galaxy contains little to no gas.
