Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the united kingdom. these organisms are unique because they can undergo a special chemical reaction at night that defend them against predators. it provides defense by attracting larger predators that prey on the organisms that eat ceratium fusus. which characteristic of ceratium fusus is being described? photosynthesis. glass-like cell walls. bioluminescence. chitin cell walls.

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. 

Advection fog occurs when warm air blows over a cold surface like snow and since tropical water is warm advection fog rarely forms over it
