Assume that you have a stock solution of epinephrine at a concentration of 1 mg/ml. knowing that the pipette you will use delivers 20 drops/ml,
calculate the number of drops of the stock solution that must be added to a smooth muscle bath containing 25 ml of locke’s solution so that the final concentration of epinephrine in the muscle bath will be 100 µg/ml, and
compute the dilution factor which describes the extent to which a single drop of stock drug solution is diluted when added to the smooth muscle bath.
number of drops = [ select ] ["54", "55.6", "20", "2.78"]
dilution factor == [ select ] ["0.25", "0.002", "4", "501"]

On edgenuity it is d: watermelons 

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. 

Yes yes yes very good

It would be like the 70's song "it's raining men".
