In fruit flies (Drosophila), one eye color gene is x-linked, with a recessive white allele and a dominant red allele. If white-eyed female flies were bred to red-eyed male flies, what would be the expected offspring (assume all parental flies are purebred)?

i'm pretty sure it's spores

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
