Explanation / Answer
1) The correct option is e. Blood Urea Nitrogen (BUN).
Blood urea nitrogen (BUN) is non-protein nitrogenous substance of the body which specifies the health of kidneys.
2) The correct option is c. Type AB.
AB blood type does not have any antibodies in the plasma, therefore it can receive any type of blood. So, it is a universal recipient.
3)The correct option is a. Monocytes.
During hemopoiesis, some of the myeloid stem cells differentiate into monocytes.
Myeloid stem cells produce neutrophils, monocytes, eosinophils, basophils, mast cells, megakaryocytes, and erythrocytes.
4) The correct option is a. Erythropoietin.
Erythropoietin hormones stimulates the proliferation of red blood cells in red bone marrow.
