How is seawater's salinity expressed
Web8 mrt. 2024 · Salinity refers to how much dissolved salts are in the water. This measurement is typically expressed in percentage or parts per thousand. To obtain this … Web15 dec. 2009 · Teleosts address this challenge by drinking seawater and taking up both salt and water across the gut, while excess sodium and chloride are secreted by the gill. Thus, the transition from freshwater to seawater requires that the gill reverse its function from an ion uptake to a salt secretory organ.
