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:

A spiral galaxy has a distinct spiral - arm structure, which gives it a pinwheel - like appearance. Spiral galaxies do have new star formation (unlike some elliptical galaxies which may have little to no new star formation). They are not made only of gases but also contain stars, dust, etc. And they are not necessarily smaller than other types of galaxies (for example, some spiral galaxies can be quite large).

Answer:

It is shaped like a pinwheel.
