Which statements describe elliptical galaxies? Select the two correct answers.(1 point)
They include the universe's largest galaxies.
They include the universe's largest galaxies.
They typically contain very little gas and dust.
They typically contain very little gas and dust.
They are the most common galaxy type.
They are the most common galaxy type.
They include the Milky Way.
They typically contain very little gas and dust.
Elliptical galaxies do not typically contain very little gas and dust.
The correct statements describing elliptical galaxies are:
1. They typically contain very little gas and dust.
2. They are the most common galaxy type.
The two correct statements are:
1. They typically contain very little gas and dust.
2. They are the most common galaxy type.
To arrive at these answers, let's break down each statement:
1. "They include the universe's largest galaxies" - This statement is incorrect. Elliptical galaxies, although large, are not the largest galaxies in the universe. The universe's largest galaxies are actually known as supergiant galaxies or giant elliptical galaxies.
2. "They typically contain very little gas and dust" - This statement is correct. Elliptical galaxies are known to have very little gas and dust compared to other galaxy types, such as spiral galaxies. Their flattened, ellipsoidal shape contributes to the lack of gas and dust.
3. "They are the most common galaxy type" - This statement is correct. Elliptical galaxies are indeed the most common type of galaxy in the universe. They make up a significant portion of the galaxies we observe.
4. "They include the Milky Way" - This statement is incorrect. The Milky Way is actually classified as a barred spiral galaxy, not an elliptical galaxy.
