Responses

its distance from the other galaxy
its distance from the other galaxy

its size compared to that of the other galaxy
its size compared to that of the other galaxy

its proportion of gas compared to that of the other galaxy
its proportion of gas compared to that of the other galaxy

its age compared to that of the other galaxy

Answer 1

The two correct answers that most likely affect whether a galaxy will evolve by merging with a second galaxy are:

1. **its size compared to that of the other galaxy**
2. **its proportion of gas compared to that of the other galaxy**

The size of the galaxies can influence gravitational interactions during a potential merger, while the proportion of gas can affect star formation rates and the dynamics of the merger process.
