The immediate effect of ADH on the renal tubules of frogs and mice is the same, yet when ADH is secreted, frogs produce urine that is approximately isosmotic to their blood plasma, whereas mice produce urine far more concentrated than their blood plasma. Explain this difference in terms of the factors affecting osmosis in the kidneys of frogs and mice.
