The apparent redshift is caused by the Doppler Effect; the frequency of waves is increased by an approaching source and decreased by a leaving source. Since the fgrequencies we see from stars are slightly lower than they should be, we know that the stars and other objects are moving away. The Doppler Effect causes changes of light emanating from distant stars and galaxies.

The spectral lines from distant galaxies do not match spectral lines on Earth due to?
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
How the expansion of space could cause a red shift in the light from distant galaxies?
The expansion of space causes a redshift in the light from distant galaxies due to the stretching of wavelengths as the universe expands. As light travels through expanding space, its wavelength increases, shifting it toward the red end of the spectrum. This phenomenon, known as cosmological redshift, occurs because the space between galaxies is increasing, leading to longer wavelengths by the time the light reaches us. Consequently, more distant galaxies appear redder, providing evidence for the expansion of the universe.
Will global warming change the next coming years?
There is every indication that it will cause drastic changes in the coming years.
What are the waves that are produced by stars and galaxies?
Density waves (they cause the spiral arms in disc galaxies).
Relationship of red shift and the big bang theory?
The Big Bang theory predicts an expanding universe. The red shift, being the Doppler effect of light when something is receding from you, confirms this because when looking at galaxies the light emitted from them is red shifted. The farther away galaxies have a higher red shift, confirming that all galaxies are moving away from each other, not just the Milky Way (i.e. the universe is expanding).
Why is the Hubble Telescope so successful at taking images of distant parts of the Universe?
Whenever Earth-based telescopes try to take images of distant objects, the image is always blurry due to atmospheric turbulence. Also, if the telescope is situated near a city, the street lights cause light pollution and dim the light coming from stars and galaxies. The Hubble Space telescope is situated above the atmosphere, so the images are crisp and sharp. Also city lights don't affect it. It can also take more images as it is not affected by day and night.
Can two galaxies combine together?
Galaxies do combine or merge together. In about 4.5 -> 5.5 billion years time time, the Andromeda Galaxy will combine with our galaxy, the Milky Way Galaxy. In a lot of cases Irregular Galaxies are believed to have formed with interactions with other galaxies. See related link for a picture of two galaxies merging.
How might an amino acid change at a site distant from the active site of the enzyme alter the enzyme's substrate specificity?
An amino acid change distant from the active site can impact the enzyme's conformation and flexibility, leading to changes in the active site shape and size. This can alter how substrates bind to the active site, affecting substrate specificity. Additionally, changes in distant amino acids can cause conformational changes that transmit through the protein, ultimately affecting enzyme-substrate interactions.
What is the french lointaine?

What force draws two galaxies towards each other?
The force that draws two galaxies towards each other is gravity. The gravitational force between the two galaxies pulls them towards each other and can cause them to collide or interact.
What shows the galaxies expanding?
Yes ...why.. well there is a theory that once the universe was as small as a match's red head? i don't know what it's called what ever...so when that bead explodes and it expands. and scientists believe that it keeps expanding. Another question you should ask your self is if that the universe was that small what was around it? answer it cause i wanna know and hope this helps!
Can you smell rain coming?
The change in humidity in the air before a rainstorm can sometimes cause a change to the smell of the air but not for all rain showers and not everyone will notice these changes.
