Question

a deficiency of which of the following intermediate cells would result in a marked increase in the clotting time of blood?
multiple choice
lymphoblast
proerythroblast
monoblast
megakaryoblast
myeloblast

Explanation:

Megakaryoblasts develop into megakaryocytes, which produce platelets. Platelets are crucial for blood clotting. A deficiency in megakaryoblasts would lead to fewer platelets, thus increasing blood - clotting time. Lymphoblasts develop into lymphocytes (involved in immune response), proerythroblasts into red blood cells (for oxygen transport), monoblasts into monocytes (immune - related), and myeloblasts into granulocytes (immune function).

Answer:

Megakaryoblast
