B. Now balance the input/output formula by adding coefficients to each molecule. Write the balanced formula below, and then check your work by clicking Balance. ___ + ___  ___ + ___

Answer:
CO2 + H2O ⇒ C6H12O6 + O2 - input formula.
6CO2 + 6H2O ⇒ C6H12O6 + 6O2 - withdrawal formula.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
