Question

which type of galaxy has arms that contain sites of active star formation and start close to a bulge in the center?
○ elliptical
○ irregular
○ barred spiral
○ normal spiral

Explanation:

• Elliptical galaxies lack distinct spiral arms and have little active star formation.
• Irregular galaxies have no defined spiral structure or central bulge arms.
• Barred spiral galaxies have arms starting from a central bar, not the bulge directly.
• Normal spiral galaxies have spiral arms that originate near the central bulge, and these arms are regions of active star formation due to dense gas and dust.

Answer:

normal spiral
