Humans are altering the carbon cycle by . (5 Points) killing off large numbers of animals, which reduces the amount of carbon in the system growing crops, which increases the amount of carbon in the system increasing their population, which reduces carbon dioxide from the atmosphere burning fossil fuels, which adds carbon dioxide to the atmosphere extracting fossil fuels from the ground, which removes carbon from the system

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.
