Answer

  1. Oval and nucleated

Explanation:

Camels have to live without food and water for a long time. Their RBCs have an oval shape unlike those of other mammals, which are circular. This facilitates the flow of red blood cells during dehydration and makes them better at withstanding high osmotic variation without rupturing when drinking large amounts of water.
