3) excess carbon gases released into the atmosphere cause additional radiation to be retained and earth's average temperature to increase. this phenomenon is known as a) solar radiation. b) the ozone shield. c) the greenhouse effect. d) industrial air pollution.

C) The greenhouse effect.
It is an increase in the average temperature of the Earth, occurring when certain gases absorb heart that would be radiated into space.

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.
