Describe the role of photosynthesis in oxygenating the atmosphere and lirik to photosynthesis in eukaryotic organisms.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
