Identify where the mutation occurred in the above sequence.

What type of mutation is it?

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

every el niño cycle is different. every year.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

not only is it colder, it also becomes darker, less salty, and more dense.
