The two factors that are most likely to affect whether a galaxy will evolve by merging with a second galaxy are its size compared to that of the other galaxy and its proportion of gas compared to that of the other galaxy.
The 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
The two correct factors that are most likely to affect whether a galaxy will evolve by merging with a second galaxy are:
1. Distance from the other galaxy: The distance between two galaxies plays a crucial role in determining the likelihood of a merger. If two galaxies are located close to each other, their gravitational interaction will be stronger, increasing the chances of a merger occurring.
2. Size compared to that of the other galaxy: The relative sizes of the galaxies involved also influence the likelihood of a merger. Generally, when a smaller galaxy interacts with a larger one, it has a higher probability of being consumed or merged into the larger one.
To determine if these factors affect whether a galaxy will evolve by merging, scientists study the position and properties of galaxies using observational data from telescopes. They measure distances between galaxies as well as their relative sizes and compare them to understand the likelihood of mergers occurring.
