Answer 2

A: An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile.
B: A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in approximately two-thirds of all spiral galaxies. Bars generally affect both the motions of stars and interstellar gas within spiral galaxies and can affect spiral arms as well.
C: Some irregular galaxies are the result of gravitational interactions or collisions between formerly regular galaxies. Many irregular galaxies orbit larger regular ones; the Magellanic Cloud galaxies orbiting the Milky Way are examples.
D: a galaxy in which the stars and gas clouds are concentrated mainly in one or more spiral arms.

Answer 3

thus, the answer is........

Answer 4

It will be elliptical galaxy i think

Answer 5

what do you think @praetorian.10 ?

Answer 6

my father would definately know but he's in hospital so i am going to have to guess and agree with @Abhisar

Answer 7

The materials they gave me for this lesson don't really describe anything of this nature, and it's a little irritating now. I have read through the entire presentation, which they have said is all I need to complete the course lesson, but it hasn't. I'm going to say yeah, it seems Elliptical galaxy is the answer. Thanks for the input!
