Which statements describe elliptical galaxies? Select the two correct answers.(1 point) Responses They typically contain very little gas and dust. They typically contain very little gas and dust. They include the Milky Way. They include the Milky Way. They are the most common galaxy type. They are the most common galaxy type. They include the universe's largest galaxies.
The two correct statements about elliptical galaxies are:
- They typically contain very little gas and dust.
- They include the universe's largest galaxies.
The correct statements about elliptical galaxies are:
1. They typically contain very little gas and dust.
2. They are the most common galaxy type.
To identify the correct answers, we can start by understanding the characteristics of elliptical galaxies. Elliptical galaxies are classified based on their shape, appearing as elongated or flattened spheres. They are often smooth and lack defined structures like spiral arms.
Statement 1, "They typically contain very little gas and dust," is correct. Elliptical galaxies are largely composed of old stars and have used up much of their gas and dust through previous star formation. This lack of gas and dust leads to less ongoing star formation in elliptical galaxies compared to other types.
Statement 2, "They are the most common galaxy type," is also correct. Observations and studies have shown that elliptical galaxies are indeed the most prevalent type of galaxy in the universe.
Therefore, the two correct statements are:
1. They typically contain very little gas and dust.
2. They are the most common galaxy type.
The two correct answers are:
1. They typically contain very little gas and dust.
2. They are the most common galaxy type.
