Which of the following demonstrates the correct sequence of events that occurs during protein synthesis? 1. trna binds to the ribosome 2. dna is used as a template to create mrna 3. amino acids are bonded together to make a polypeptide 4. mrna molecule binds to a ribosome 5. the ribosome releases both the mrna molecule and the polypeptide a. 1,2,3,4,5 b. 2,4,3,5,1 c. 4,2,1,5,3 d. 2,4,1,3,5

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
