Indicate whether the following statements are most true for
elliptical or spiral galaxies.
(Select S-Spiral, E-Elliptical. If the first is S and the rest E,
enter
SEEEEE).
PLEASE ANSWER ONLY IF YOU ARE 100% POSITIVE. THIS IS MY SECOND TIME
POSTING IT BECUSE BOTH ANSWERS I HAVE RECIEVED ARE WRONG
A) Are rare in the central regions of galaxy clusters.
B) Most numerous type in the Universe.
C) Contain abundant clouds of cool gas and dust.
D) Has a very large range in size and mass.
E) Has no current star formation.
F) Contain no hot, massive stars.
G) Are more reddish in color.
SESEEEE
A) Elliptical galaxies are mostly found at the center of galaxy clusters.
B) The dwarf elliptical galaxies are probably the most common type of galaxy in the universe.
C) Spiral galaxies contain abundant clouds of dust and gas.
D) Elliptical galaxies vary greatly in both size and mass with diameters ranging from 3000 lightyears to more than 700,000 lightyears, and masses from 105 to nearly 1013 solar masses.
E) Elliptical galaxies do not contain abundant gas and dust. So the star formation probability is extremely small in elliptical galaxies.
F) Spiral galaxies have a huge amount of hot massive stars in their spiral arms.
G) Elliptical galaxies are redder in color. Spiral galaxies are red in color in the center and blue color in arms and bars.
