4. Which of the following equations represents the right chemical process that occurs in photosynthesis?
A. Six molecules of water plus six molecules of hydrogen plus six molecules of oxygen converts light energy plus sugar.
B. Six molecules of carbon dioxide plus six molecules of water plus light energy converts six molecules of oxygen plus
sugar.
C. Six molecules of carbon dioxide plus sugar plus light energy converts six molecules of carbon and six molecules of
oxygen.
D. Six molecules of oxygen plus six molecules of water plus light energy converts six molecules of carbon dioxide plus
sugar.

The right answer is B)

Photosynthesis equation:

6CO2 + 6H2O + Sunlight > 6O + C6H12O6

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.
