They typically contain very little gas and dust.
They include the universe's largest galaxies.
They include the universe's largest galaxies.
They include the Milky Way.
They include the Milky Way.
They are the most common galaxy type.
The correct statements are:
1. They typically contain very little gas and dust.
2. 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 include the universe's largest galaxies.
The correct answers are:
1. They typically contain very little gas and dust.
2. They include the universe's largest galaxies.
To determine the correct answers, we need to understand the characteristics and properties of elliptical galaxies.
Elliptical galaxies are a type of galaxy with an elliptical or oval shape. They differ from spiral and irregular galaxies, which have a more flattened disk shape or irregular structure.
Statement 1: They typically contain very little gas and dust.
Elliptical galaxies are often referred to as "red and dead" galaxies because they have used up most of their gas and dust. This means they have lower levels of these elements compared to other types of galaxies.
Statement 2: They include the universe's largest galaxies.
Elliptical galaxies can be significantly larger than other galaxy types. They can range in size from relatively small to massive giants, containing billions to trillions of stars.
Statement 3: They include the Milky Way.
This statement is incorrect. The Milky Way is a barred spiral galaxy, not an elliptical galaxy.
Statement 4: They are the most common galaxy type.
This statement is also incorrect. Spiral galaxies, like the Milky Way, are more common in the universe compared to elliptical galaxies.
Therefore, the correct answers are that elliptical galaxies typically contain very little gas and dust, and they include the universe's largest galaxies.
