Question 7 0 / 1 pts Saltwater fishes typically: lose water and gain salt across their gills lose water and lose salt across their gills e do not lose or gain significant water or salt across their gills gain water and lose salts across their gills gain water and lose salt across their gills
Question 3 0/1 pts Some bony fish, such as shad, leave the ocean and return to their natal freshwater streams to breed. When their environment changes from salt water to freshwater, these fish are likely to show a decreased movement of water from the environment into body tissues. produce an increased volume of more dilute urine. maintain the same direction of ion-pumping across their gills. decrease the absorption of ions in their guts. increase their drinking rate.
Marine bony fish maintain homeostasis by excreting a small volume of dilute urine and retaining salts. excreting copious amounts of concentrated urine and pumping salts from their gills. excreting small amounts of urine nearly isosmotic to plasma and pumping salts from their gills. excreting copious amounts of dilute urine and retaining salts. conserving both water and salts.
Question 10 0/1 pts At present, there are no osmotic conformers in any freshwater animal species on Earth. Why? Freshwater has an osmolarity of O, and no animal could survive with such a low plasma osmolarity. The statement is incorrect: there are osmotic conformers in freshwater environments Marine animals have been in existence much longer than freshwater animals, and evolution of osmotic conformity has not occurred in freshwater animals yet Marine environments are much more abundant on Earth than freshwater environments, allowing for more diversity of animal forms. Osmotic conformers must expend a great deal of energy and evolution favors adaptations that conserve energy
