Outflow of the sympathetic division occurs from which regions of the cns

Answer – Thoracic and Lumbar

Outflow of the sympathetic division occurs from the THORACIC AND LUMBAR regions of the Central Nervous System (CNS). To be precise, the preganglionic fibers of the sympathetic division arise from spinal cord segments T1 to L2.

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

not too sure but maybe in the hot springs.
