Just about everything in the Icy waters off the coast of Antarctica is in the same state--frozen. Yet one type of fish, called a notothenlold, remarkably does not freeze in the frigid environment. In a recent study, scientists were able
to better understand a genetic alteration in the fish. As it turns out, antarctic notothenlolds produce a substance
that acts as antifreeze. Antifreeze is a term familiar to car owners. It is a substance that keeps the water inside an
automobile engine from freezing. Notothenlolds manufacture their own "antifreeze proteins." These proteins lock
on to ice crystals in their blood.

Should be D, adapted. I don't see how the fish enlarged or departed anywhere, and it didn't waver, but it has a special adaptation to the cold, so the best answer is adapted.
