How do the cellular components of frog blood differ fundamentally from mammalian erythrocytes, and how does frog lymph compare to frog blood?

1. A
   Frog RBCs are enucleated with haemoglobin; lymph contains more erythrocytes than whole blood.
2. B
   Frog RBCs are nucleated and contain haemoglobin; lymph lacks RBCs and a few proteins compared to blood.
3. C
   Frog erythrocytes completely lack haemoglobin; lymph contains high concentrations of platelets and albumin.
4. D
   Frog RBCs are spherical and non-nucleated; lymph contains identical protein and cellular fractions to blood.
