How can the wavelengths of light from a distant galaxy be used to determine the distance between Earth and the galaxy?
A The color of light from a galaxy indicates the age of the galaxy, and the most distant galaxies are the
oldest.
B The light from distant galaxies shows a shift to longer wavelengths, and the shift increases as the distance
increases.
C The light from a distant galaxy is scattered by dust in the space between Earth and the galaxy, and the
amount of scattering indicates distance.
D The most distant galaxies emit the most light in the x-ray part of the spectrum, and the distance can be
determined based on the strength of this light.

answer: i don't know the answer good luck

explanation:

this is a good question! i'll do some research and come back when i have the answer!

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
