2. are rare in central regions of galaxy clusters
3. contain many bright, hot stars
4. are more reddish in color5. contain primarily old, low-mass stars
6. contain abundant clouds of cool gas and dust
7. have significant, ongoing star formation

Answer:

  • 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.
