1. What traits to all organisms (prokaryotes and eukaryotes) share? 2. Be able to understand the arguments against a separate Class Aves and a separate Domain Eukarya from paraphyly. 3. What do gram-positive and negative refer to? 4 What do high and low GC refer to? 5 What is the dormant form and some representative examples of low-GC gram-positive bacteria?

The answer is c) organisms that are sensitive to changes in temperature would die.

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.
