Diuretics are the external chemical that enhances urinary output. Urinary system regulates chemical and volume which makes up blood. It also maintains the balance between salts and water and bases and acids.

It acts as an activation of vitamin D. It is in urinary system where we find the urinary bladder which provides storage reservoir for urine. We have urethra which transports urine out of the body from the bladder.

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.
