Mark turned quickly, pivoting on his right foot, while he was playing basketball. he felt a sudden, sharp pain in his knee and found his leg would not support him well. when he tried to walk off the court, his knee wobbled sideways. based on this evidence, which of the following has he most likely injured?

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
