Question

Suppose that the mice with unlimited access to water produced more urine than the mice given no access to water. how would that difference in urine production affect your ratio calculations for the two groups? (remember that the ratio is urine osmolarity divided by blood osmolarity.)

Answer 1

The ratio of both groups would stay the same. Reason being the ratio in urine osmolality is divided by blood osmolality. The mice with no access to water the ratio of urine osmolality to blood osmolality are 14:7 while for mice with unlimited access to water the ratio of urine osmolality to blood osmolality is 1:4. In conclusion, the mice with no access to water produce highly concentrated urine.
