1.^ The given graph shows the concentration of urine produced in three different mammals, A, B
and C.
Three types of kidney tubules, X, Y and Z, are also given below.
Length of loop of Henle may vary in different
kidney tubules and is related to urine
concentration.
i. What is the reason for the production of different
concentrations of urine in these mammals?
-----------------------------------------------------------------------------------.
ii. Refer the graph and match the kidney tubules (X, Y and Z)
with the mammals (A, B and C) to which they belong.
