a. 4–2–3–1
b. 2–4–3–1
c. 2–3–4–1
d. 4–1–3–2

Hemocytes are stem cells which become red blood cells (RBC). The RBC's are filled with a protein called hemoglobin. Such a cell product is stored in cell structures that are? A) Formed from the nucleus B) Formed as Vesicles from the Endoplasmic reticulum C) engulfed in to the cell by pinocytosis D) Released in to the blood by exocytosis E) Ingested by Phagocytosis
And explain why
a) In some cases the phagocytosis failed. formulate 2 hypothesis to explain the origin of this failure?
b) Name in this case, the cells that will be involved to help the body.
Removal of apoptotic cells are done by:
Question 6 options:
a)
phagocytes or neighboring cells.
b)
circulatory system sweeping away the fragmented cells.
c)
fragmentation of the cell into small enough pieces that they are swept away by extracellular fluid.
d)
fusion of the apoptotic cell to neighboring cells to form multinucleate cells.
e)
migration of the apoptotic cells from the tissue to the lymphatic system to be flushed out.
