What is important about the Hubble telescope's discovery that there is a red shift in the spectra of galaxies?
The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
How would other galaxies appear to move relative to Earth if the universe were shrinking?
If the Universe was shrinking the galaxies would appear to be moving towards the Earth, and look more blue than they should. This is the opposite to the universe expanding where galaxies would appear to be moving away from the Earth, which we know due to "red shift". Andromeda would be the exception since it's directly moving towards the Milky Way.
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?

Are there galaxies with no supermassive black holes?
Yes. Some galaxies, particularly irregular galaxies, appear to lack supermassive black holes.
Why can you use line spectra to measure the speed of galaxies?
The Doppler effect changes the position of well-known lines.
The spectra of most galaxies show redshifts this means that their spectral lines are what?
shifted towards the red end of the spectrum
What did the discovery of background radiation distributed evenly throughout the universe provide support for?
either starlight spectra or moving galaxies.
What are similarities between elliptical and spiral galaxies?
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Where can you find an IR Spectra for Potassium Oxalate monohydrate and what is the spectra number?
Best guess would be the Sadtler spectra; no idea what the number would be.
The spectra of most galaxies show redshifts this means that their spectral lines?
have wavelengths that are longer than normal:)
