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 shrinks2. most protogalactic gas settles into a disk3. protogalactic cloud has high density4. a galaxy collision strips away gas5. protogalactic cloud rotates very slowly6. protogalactic cloud has high angular momentum
