In which situation would new technology be most likely to cause a change in an existing theory about new structures a cell? The new technology makes it possible to detect and analyze a structure more rapidly. The new technology allows scientists to confirm the presence of an existing structure in a cell. The new technology makes it possible to produce additional structures that were not previously there. The new technology allows detection of a structure that could not be detected previously.

When you are making a guess you are forming a hypothesis

Very hard to understand

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.
