Astronomers suspect that a galaxy’s type can be affected both by the conditions in the protogalactic cloud from which it forms ("initial conditions") and by later interactions with other galaxies.
each item below describes either a condition in a protogalactic cloud or a later interaction.
match these items to the galaxy type you would expect to form as a result.
1. stars form rapidly as the protogalactic could shrinks.
2. most protogalactic gas settles into a disk.
3. protogalactic cloud has high density.
4. a galaxy collision strips away gas.
