What characteristics separate algae from protozoans and plants?

Algae has very similar structures with land plants. However, these structures are not as quite complex as land plants. For example, algae have chloroplast a, which is also found in plants. Algae can also go through photosynthesis, but not as well as gymnosperm/angiosperm, or anything with a vascular tissue.

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.
