During a severe windstorm on an isolated island, some pollen and seeds from conifers are carried high into the air in a cloud of dust. In which of these situations would the dust cloud containing the seeds and pollen be considered an agent for gene flow? А. The dust cloud is subjected to an extended period of ultraviolet radiation, causing a mutation in a gene of
the conifer seeds.

B. The dust cloud settles, and a few of the conifer seeds return to the same environment.

C. The dust cloud is subjected to electromagnetic radiation from the sun, causing the pollen to be unable to
pollinate flowers.

D. The dust cloud settles over a forest on a distant, isolated island and pollinates some conifer trees in that forest

A.) The dust cloud is subjected to an extended period of ultraviolet radiation, causing a mutation in a gene of the conifer seeds.

I think that this one is the most likely answer, however C also makes sense whereas is gives an explanation as to how the structure of the seeds might be affected. However, it doesn't seem right to say that it was caused by and electromagnetic radiation considering the fact that the radiation is based more around electromagnetism. Both of these answers may seem unlikely to you so I'm going to try to make an explanation for one of the others to give you better insight on what could be the answer. If some of the seeds manage to make it to a different area with possibly different soil, then it is possible that the seed would need to mutate in order to survive the conditions of the area around it.

Hope this helps.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
