How many times did a true "kidney" evolve in the animal clade. Which cases are clearly homologous (one evolutionary origin), and which must have evolved by convergent evolution and are therefore analogous?
1) Compared to those of similarly sized birds and lizards, the kidneys of mammals ______.
A) have larger glomeruli, but shorter nephron loops
B) have larger glomeruli, but shorter nephron loops
C) have lower concentration of urea in their renal medulla
D) have higher concentrations of Na+ and Cl- in their renal medulla
3. The purpose of this research was not to test the functionality of the transplanted kidneys, but whether or not the human body would reject them. Why are the researchers excited that the kidneys produced ‘robust’ urine and were able to withstand the higher human blood pressure exerted on kidneys in a human body
