Question

Why do camel have a nucleus in their nucleus?

Answer 1

nucleated red blood cells? ... Like in all mammals, camel erythrocytes(RBCs) do have a nucleus and other organelles when first formed (in bone marrow), and in all mammals, these are ejected upon maturity (making more room for oxygen transporting hemoglobin).

Answer 2

If all nuclei of mass number A were to be allowed to be constructed of A neutrons, then 56Fe would release the most energy per nucleon, since it has a larger fraction of protons than 62Ni.
