Question

Which factors are most likely to affect whether a galaxy will evolve by merging with a second galaxy? Select the two correct answers.(1 point)

its proportion of gas compared to that of the other galaxy

its distance from the other galaxy

its size compared to that of the other galaxy

its age compared to that of the other galaxy

Answer 1

1.Gravity acts on existing material, shaping it into a new form.

2.a much larger galaxy, a nearby galaxy

3.low gas content, little star formation

Step-by-step explanation:

i just did the test and its 100%. dont believe me? just do the test and see for your self

Answer 2

ii. its distance from the other galaxy.

iii. its size compared to that of the other galaxy

Step-by-step explanation:

A galaxy is a vast constituent of interstellar medium of gas, dust and billions of stars bounded by the gravitational pull. There are tens of billions of galaxies existing in the whole universe. Various numbers of galaxies can merge to form an inter-cluster, which is a more massive and bigger galaxy.

The constituent of an individual galaxy are held together by mutual gravitational pull, but may interact with other galaxies depending on; its distance from other galaxies and its size compared to that of the other galaxy. This process would result into the formation of a giant elliptical galaxy and a number of stars.
