If it takes 2 hours for a population of bacteria to grow from 100 cells to 1600 cells, what is the generation time of this bacterial species? if it takes 2 hours for a population of bacteria to grow from 100 cells to 1600 cells, what is the generation time of this bacterial species? 30 minutes 20 minutes 40 minutes 15 minutes

30 minutes
It takes 4 generations to go from 100 to 1600 bacteria. Therefore 2 hours (120 mins)/4 = 30

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.
