Question

two types of spiral galaxies exist. a normal spiral galaxy is one kind. which phrase best describes the second type of spiral galaxy?
○ is football - shaped
○ is irregularly shaped
○ has arms that start close to the center
○ has a bar through the middle from which arms extend

Explanation:

Spiral galaxies are divided into two main categories: normal spiral galaxies and barred spiral galaxies. Barred spiral galaxies have a distinct central bar structure, with spiral arms extending outward from the ends of this bar. The other options are incorrect: football-shaped describes elliptical galaxies, irregularly shaped describes irregular galaxies, and arms starting close to the center is characteristic of normal spiral galaxies.

Answer:

D. has a bar through the middle from which arms extend
