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

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

Correct answer · Option 2

Frog RBCs are nucleated and contain haemoglobin; lymph lacks RBCs and a few proteins compared to blood.

Explanation

In frogs, RBCs are nucleated and contain haemoglobin. Lymph differs from blood because it lacks RBCs and a few proteins.
