SOMEONE PLEASE HELP!

1. Open the Shifting Light Spectra activity. When prompted, use the slider to move the galaxy as directed. Describe how the galaxy’s spectrum changes as it moves away from and toward the blue planet?

2.When prompted, explore further. Select each galaxy to see its spectrum. Select blue or red to indicate if the galaxy’s spectral lines show redshift or blueshift. Then choose whether the change in spectral lines would indicate a diverging and expanding universe or a converging and shrinking universe
