A marine ray (a euryhaline, osmoconforming, ionoregulator) moves its way from seawater to freshwater, swimming up a river. Which of the following events is MOST likely to occur? A decrease in the volume of urine produced A decrease in the activity of active transport pathways that increase uptake of Na from the environment. A decrease in the passive loss of Na from the animal. A decrease osmolarity of the blood as the animal moves from seawater to freshwater.
