How does electromagnetic spectrum related to expanding universe

(This is not biology)

Some of the proof that the Universe is still expanding is the Doppler Effect, which consists of : when radiation is emitted, its frequence is higher the closer it is to the object receiving that radiation. So when explaining the universe expansion cientists base on the fact that the radiation emitted by the planets are reducing their frequences gradually.

I tried my best, I hope this helps!

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
