Question

Quizplus · Accepted Answer

The rate of star formation in a protogalaxy plays a crucial role in determining whether it evolves into a spiral or an elliptical galaxy. High rates of star formation can lead to the development of spiral arms, characteristic of spiral galaxies, while lower rates might result in the more uniform distribution of stars seen in elliptical galaxies.
