The correct answer should be C. bio-luminescence
They have this ability because the parts that are shiny are meant to be like bait for other animals and when they come near to eat it or check it out they get eaten by the entire fish which is much larger than its bioluminescent part.
I think it's A but here's an explanation anyway: as you heat the crude oil, the different hydrocarbons, having different boiling points, boil and evaporate up the column. Those with lower boiling points, shorter in chain length, will condense nearer the top of the fractional distillation column. Those that are more viscous, larger in chain size, will have high boiling points, so will evaporate last and condense lower down in the column. Therefore, you achieve all the different oils / materials (oil, petrol, gasoline, tar etc etc). I hope this helps. If not, then a good website to use is 'BBC bitesize, fractional distillation'.

<u>Explanation:</u>
First, we may wonder what Pangaea Ultima is? In simple terms, according to Geologist, Christopher Scotese, he hypothesized that the structure of our continent as we know today will be restructured or merged together into a single contiguous continent.
In regards to the Philippines, it is believed that it will be no longer a country but will be crushed and turned into <u>a mountain range</u> that will exist between Australia and Eurasia.
Thus, we can conclude that if the Philipines become a "mountain range", this will result in people's livelihood been affected; furthermore, they'll have to migrate to other countries, affecting transportation, biodiversity and even health because of the change in temperature.
