if we consider the formation of RBCs Erythropoietin, produced by the kidneys, signals RBC formation in the red bone marrow is required. but if we consider the activation of rbc so haemoglobin is essential, in which haemoglobin consiats of single molecule so we can also say for the activation of rbc that:- IRON------>HAEMOGLOBIN------>RBC and RBC are produced as BY KIDNEY------->ERTHROPROTEIN------>RBC

There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone.

There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
RBC of all the mammals is anucleated without any exception. RBC of mammals are nucleated only during embryonic stages. It's just that RBC's of camels and llama are oval in shape and anucleated.
