Answer:

The "dark matter" is responsible for giving a "galaxy its particular shape".

Explanation:

  • In a galaxy, it is mainly the dark matter that holds the galaxy together. A galaxy that is in motion exerts centrifugal force on the planets, stars and other material.
  • This force tends the planets and stars to move away from the "center of the galaxy".
  • On the other hand, the dark matter deploys gravitational force on the material present in the galaxy which holds it in its place.
