Which statement correctly describes the role of dark matter in galaxy formation?

Question

Quizplus · Accepted Answer

Dark matter is believed to be the framework on which galaxies form. The initial density fluctuations in the universe that led to the formation of galaxies were thought to be caused by slight variations in the density of dark matter. These areas of higher density in dark matter then attracted and accumulated baryonic matter (normal matter made up of protons, neutrons, and electrons), eventually leading to the formation of galaxies. Therefore, where dark matter collects, the baryons follow.
