Light from the galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.' As the objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift, most galaxies in the universe exhibit redshift, i.e., option D.
<h3>What are redshift galaxies?</h3>
Most other galaxies are moving away from others since 1929, when Edwin Hubble discovered that the Universe is expanding. Light from these galaxies is shifted to longer (and thus redder) wavelengths - it is 'red-shifted.'
Redshift is the displacement of an astronomical object's spectrum toward longer (red) wavelengths. It is attributed to the Doppler effect, which is a change in wavelength caused by the motion of a given source of waves and an observer with respect to each other.
As objects in space that are moving away from Earth exhibit redshift, and objects in space that are moving toward Earth exhibit blueshift. It shows that most galaxies in the universe exhibit redshift.
Thus the correct option is D.

At the end of the winter they are most numerous in fresh water. they will cover surface of aquatic plants or poles and wooden borders of ponds. If you like to study them you can scrape the brown growth with a flat piece of plastic. you can also use a sponge. for the free living (plankton) species fine mesh plankton net is very useful.
The original source of energy in a food chain is the sun.
