Which of the following is a difference between phase I and phase II of meiosis? Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.

Anaphase, metaphase, and telophase only occurs during phase I of meiosis.

Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.

Genetic variations can only occur during phase II of meiosis.

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. 

The first means of speeding up reactions mentioned by the speaker is raising the enzymes 

Although i don't know what is the simulated system, starfish are predators that eat mostly  microalgae,  snails, sponges, bivalves, mussels and other small marine animals. removing starfish from any system would definitely increase this animals that they prey.
