As rain mixes with chemicals such as sulfur dioxide in the air, acid rain is produced. this may result in
(a) lowering the ph in ponds, thus limiting the survival of many organisms
(b) lowering the ph in ponds, thus affecting water temperature
(c) raising the ph in ponds, thus encouraging the growth of organisms
(d) raising the ph in ponds, thus limiting animal development
(e) depleting atmospheric carbon dioxide available for photosynthesis

The answer is A. Think of stomach acid when you think of pH the stomach acid degrades and mushes the food up making it easier to digest. So acid rain will make the water acidic hurting the environment

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.
