The figure shows the Doppler Shift when the source is moving. How does this relate to light from stars? Because the universe is expanding, light waves are compressed and see brighter from more distant galaxies.

Because the universe is expanding, light from galaxies shifts toward the red end of the spectrum

Because the universe is collapsing toward Earth, light from stars shifts toward the red end of the spectrum

Starlight has no relationship to the Doppler shift shown in the figure.

b. heterotroph

explanation:

because the light is a great source of energy for the plants to survive. (i hope this )

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
