PLEASE HELP James fills a graduated cylinder with 50 mL of water. He then drops a 00g key into the graduated cylinder. The water level inside the graduated cylinder rose to 53 mL as shown below.
50 mL
53 mL

If Density - Mass / Volume, what is the density of the key?A : 60 gmL
B: 20 gimL
C: 2.05 g/mL
D: 0.05 g/mL

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : ) 

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.
