Following are a number of distinguishing characteristics of spiral and elliptical galaxies. match each characteristic to the appropriate galaxy type.

1. have a flattened disk of stars
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

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.

Your answer is d. silli hope this ! : ) i left an explanation down below if you need it: a sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. a sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. the word sill means a concordant intrusive sheet.

The answer is filtering so c
