Which of the following statements is true? both prokaryotic and eukaryotic organisms can have one or more cells. prokaryotic organisms are always unicellular, but eukaryotic organisms are always multicellular. prokaryotic organisms are always unicellular, but eukaryotic organisms can be either unicellular or multicellular. nextreset

the answer would be 3

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
