Marine organisms adapted to the coldest temperatures and the highest salinity levels would inhabit which zone?

The correct answer is: Abyssopelagic or Hadalpelagic zones, because these zones are deepest marine zones.

There are 5 main marine zones (and a few subzones):

1.Epipelagic zone (200 m) – the sunlight zone where is s most of the life in the ocean.

2.Mesopelagic (1000 m) – the twilight zone many of the organisms who live in this zone have special adaptations

3.Bathypelagic (1-4000 m) – the midnight zone

4.Abyssopelagic (4-6000 m)

5.  Hadalpelagic zones (6-11000 m).

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
