Detailed explanation-1: -Osmoregulation is an example of a negative feedback, homeostatic control system. This system detects changes in the salinity of the water Chinook salmon live in, working to keep the body water concentration constant.
Detailed explanation-2: -Negative feedback is a process where a change in the environment is detected by receptors and then effectors respond to correct that change. www.curriculum-press.co.uk. # 384. Any deviation from the set point (increase or decrease) is returned to the set point. The Importance of Osmoregulation.
Detailed explanation-3: -The stimulus-temperature, glucose, or calcium levels-is detected by the receptor.
Detailed explanation-4: -Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis. The higher the osmotic pressure of a solution, the more water tends to move into it.
