Question

identify the incorrect statement about nucleus. A.Nucleus regulates and controls all functions of a cell. B.Nucleus is absent in the mature RBC of all the mammals except camel and llama. C.Nucleus do not play a role in cell division. D.Robert brown first identified the nucleus​

Answer 1

Answer:

C.Nucleus do not play a role in cell division.

Explanation:

This is because nucleus contains DNA which is necessary of cell division

Answer 2

Answer:

A nucleated red blood cell (NRBC), also known by several other names, is a mammalian red blood cell that contains a cell nucleus. NRBCs occur in normal development as precursors to mature red blood cells in erythropoiesis, the process by which the body produces red blood cells. NRBCs are normally found in the bone marrow of individuals of all ages and in the blood of fetuses and newborn infants.[1][2] After infancy, RBCs normally contain a nucleus only during the very early stages of the cell's life, and the nucleus is ejected as a normal part of cellular differentiation before the cell is released into the bloodstream. Thus, if NRBCs are seen on an adult's peripheral blood smear, it suggests that there is a very high demand for the bone marrow to produce RBCs, and immature RBCs are being released into circulation. Possible pathologic causes include anemia, myelofibrosis, thalassemia, miliary tuberculosis, cancers involving bone marrow (myelomas, leukemias, lymphomas), and in chronic hypoxemia.[3]
