I think it's D. the moon is between the sun and earth
DNA replicates before cell division, duplicating chromosomes. This occurs during S stage of interphase! Now each chromosome has two identical double helical models.
If referring to photosynthesis, carbon dioxide is brought into the cholorplast of the plant cell, it is then fixed to RUBP, it will go through a series of Redox reactions and become G3P. RUBP is then recycled and is used to fix more carbon dioxide. You need two G3P molecules to become glucose.
I believe that would be small polar and nonpolar molecules.
Hope it helps!
