Which of the following describes the difference between biomagnification and bioaccumulation? Biomagnification occurs when chemicals build up in an environment, while bioaccumulation occurs when chemicals accumulate in
the food chain.
Biomagnification occurs when chemicals accumulate in the food chain, while bioaccumulation occurs when chemicals build up in an
environment.
Biomagnification occurs when chemicals build up in an environment, while bioaccumulation occurs when chemicals become stronger
after repeated use.
Biomagnification occurs when chemicals become stronger after repeated use, while bioaccumulation occurs when chemicals

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.
