I can't see the picture, but to do the dilation you must first figure out the coordinates of the first image and then figure out what half of it is and add that on to the new image or take that much off of the new image.
*To dilate means to make bigger or smaller
It would help to attach a picture or explain the question better. How else are we supposed to know the places the question is talking about?
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.

The energy transfer of one organism to the next? when a organism is eaten a certain percent of their meals energy is gain for example a snake eats a mouse only a small percent of that mouse's energy is past to the snake i hope this helps
