which type of galaxy has arms that contain sites of active star formation and start close to a bulge in the center?\nelliptical\nirregular\nbarred spiral\nnormal spiral
Answer
Brief Explanations:
Normal spiral galaxies have arms that start close to a central bulge and often host sites of active star - formation. Elliptical galaxies have little star - formation. Irregular galaxies lack a defined structure like arms starting from a bulge. Barred spiral galaxies have a bar - shaped structure in the center which affects the arm structure differently.
Answer:
D. normal spiral
