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.

See description

Explanation:

I will provide the matching galaxy type for each term

1. stars form rapidly as the protogalactic could shrinks. - -> this is something from an elliptical galaxy

2. most protogalactic gas settles into a disk. - - - > this belongs to a Spiral galaxy, thats why the gas settles as a disk

3. protogalactic cloud has high density. - -> this belongs to the elliptical galaxy group

4. a galaxy collision strips away gas. - -> elliptical as well

In elliptical galaxies, the protogalactic cloud has high density, also the stars form rapidly as the cloud shrinks, meanwhile in an elliptical galaxy, the gas settles into a disk
