Question

1. the universe has both clusters and voids. what is the difference between these two areas?

○ clusters are areas where there is little matter and no galaxies. in contrast, voids represent areas with many galaxies.
○ voids are areas where there is little matter and no galaxies. clusters are areas with many galaxies.
○ clusters are areas that have only elliptical galaxies, and voids are areas that have only irregular galaxies.
○ voids are areas that have only elliptical galaxies, and clusters are areas that have only irregular galaxies.

Explanation:

To solve this, we analyze each option:

• First option: Incorrect. Clusters should have many galaxies, voids little matter.
• Second option: Correct. Voids have little matter/galaxies, clusters have many galaxies.
• Third option: Incorrect. Clusters don't have only elliptical galaxies, voids don't have only irregular.
• Fourth option: Incorrect. Voids don't have only elliptical, clusters don't have only irregular.

Answer:

B. Voids are areas where there is little matter and no galaxies. Clusters are areas with many galaxies.
