If you happen to go to a desert, what changes do you expect to observe in the urine you excrete? You would

(i) Excrete small amount of urine.


(ii) Excrete large amount of urine.


(iii) Excrete concentrated urine.


(iv) Excrete very dilute urine.


Which of the above would hold true?


In a desert, there is scarcity of water. So the organisms tend to conserve water by different adaptations. Similarly, we will excrete concentrated and less amount of urine to prevent loss of water from the body.
