1. have a flattened disk of stars - - - spiral galaxies. 2. are rare in central regions of galaxy clusters - - - spiral galaxies. 3. contain many bright, hot stars - - - Spiral galaxies. 4. are more reddish in color - - - Elliptical galaxies. 5. contain primarily old, low-mass stars - - - Elliptical galaxies. 6. contain abundant clouds of cool gas and dust - - - Spiral galaxies. 7. have significant, ongoing star formation - - - Spiral galaxies

Explanation:

Most galaxies that contain a central bulge that is surrounded by a rotating disk of arms that circles the galaxies are said to be a spiral galaxy. About 60% of the galaxies are made up of spiral shapes and they are mostly found n low-density regions and are in the central of the galaxy clusters. Spiral galaxies often have beautifully shaped made form hot and young stars. The more reddish in color indicates much older galaxies and are resemble that of an elliptical shape. Also, they consist of a little amount of dust and gas left. Spiral galaxy has rich gas and high star formations.
