Question

which statement describes a characteristic of a spiral galaxy?
○ it is shaped like a pinwheel.
○ it has no new star formation.
○ it is made only of gases.
○ it is smaller than other types of galaxies.

Explanation:

Spiral galaxies have a distinct pinwheel-like structure with curved spiral arms extending from a central bulge. They actively form new stars in their arms, contain stars, gas, and dust (not just gases), and can be large (e.g., the Milky Way is a spiral galaxy, larger than many dwarf elliptical galaxies).

Answer:

A. It is shaped like a pinwheel.
