a group of middle school students were given a short course in speed-reading. the instructor was curious if a monetary incentive would influence performance on a reading test taken at the end of the course. half the students were offered $5 for obtaining a certain level of performance on the test, the other half were not offered money.
what is the control group?
what is the independent variable?
what is the dependent variable?

The control group is..$0 group(no monetary initiative)
the independent variable is the monetary incentive ($5 or no money)
the dependent variable is the performance on the reading test 

The control group is the students sans the money. The independent variable would be the 5$. The dependent variable is students receiving the money.

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.
