Why have birds and mammals evolved countercurrent mechanism to excrete hypertonic urine ? What are the components of this countercurrent mechanism ? How it works ?

Why does the camel excrete hypertonic urine?

Why does the camel excrete hypertonic urine?

How does the mechanism of heredity work ?

Countercurrent mechanism operates in loop of Henle/vasa rectae/Both of these.

Why is counter current mechanism essential for concentration of urine? Explain.

Henie's loops are found in those animals which excrete hypertonic urine. One of the following does not have Renie's loop.

Consider the following water conservation mechanism A. Nasal countercurrent mechanism B. dependence on metabolic water C. Highly hypertonic urine D. Living more on protein rich diet The kangaroo rat living in desert can survive without drinking water because of
