The two correct answers are:
1. its size compared to that of the other galaxy
2. its proportion of gas compared to that of the other galaxy
Responses
its age compared to that of the other galaxy
its distance from the other galaxy
its size compared to that of the other galaxy
its proportion of gas compared to that of the other galaxy
1. its size compared to that of the other galaxy
2. its proportion of gas compared to that of the other galaxy
1. its size compared to that of the other galaxy
2. its proportion of gas compared to that of the other galaxy
1. Age: The age of a galaxy compared to the other galaxy can play a role in their likelihood of merging. If two galaxies are approximately the same age, they may be more likely to merge due to their similar evolutionary stages. However, if one galaxy is significantly older or younger than the other, it may be less likely to merge.
2. Size: The size of a galaxy compared to the other galaxy can also influence the likelihood of merging. When galaxies of similar sizes come into close proximity, the gravitational forces between them can cause them to merge. Smaller galaxies may be more prone to being merged into larger ones.
Therefore, the two correct answers are:
- its age compared to that of the other galaxy
- its size compared to that of the other galaxy
