Which of the following is true about the ages and masses of spiral and elliptical galaxies?
A)Ellipticals are all older and more massive than spirals.
B)Spirals are older, and much more massive than ellipticals.
C)Both types are about the same age, but spirals vary less in mass.
D)Spirals are younger and much more massive than any elliptical.
E)Ellipticals are older, and show a far wider range of masses than do spirals.

Question

Quizplus · Accepted Answer

Observations have shown that spirals and ellipticals have approximately the same age, but spirals vary less in mass compared to ellipticals. Observations suggest that the ages of spiral and elliptical galaxies are similar, but there is a greater variation in the masses of elliptical galaxies compared to spirals. Therefore, option C is the correct answer.
