D- None of the above

Explanation / Answer

Question 1

Answer is TRUE.

The hemopoietic growth factors are involved in differentiation and proliferation of progenitors cells.

the hemopoietic growth factors involved proliferation are Erythropoietin, Colony-stimulating factors, Cytokines, interleukins, and thrombopoietin.  

Question 2

Answer is A (Have A and B antigens on your RBC )

Agglutination with antiserum A indicates - the RBC contains A antigen - blood group is A

Agglutination occurs with antiserum B - the RBC contains B antigen - blood group is B

Agglutination occurs with both antisera A and B - The RBC contains both A and B antigens- the blood group is AB

No agglutination with antiserum A or antiserum B – No antigen on RBC - The Blood group is O.

Question 3

Answer is C.(Platelets)

The megakaryoblasts are converted into megakaryocytes and then developed into Platelets.

Question 4

Answer is E (Biliverdin is the protein that stores iron )

The biliverdin is converted into bilirubin and it is eliminated in urine. it does not stores iron.

Question 5

Answer is B (Natural killer cells)

These cells provide innate immunity. It is the type of lymphocyte and fights against the newly formed tumor cells and viral infections.

Question 6

Answer is A (AB negative)

Agglutination with antiserum A indicates - the RBC contains A antigen - blood group is A

Agglutination occurs with antiserum B - the RBC contains B antigen - blood group is B

Agglutination occurs with both antisera A and B - The RBC contains both A and B antigens- the blood group is AB

No agglutination with antiserum A or antiserum B – No antigen on RBC - The Blood group is O.

The Anti- Rh serum is used to detect the presence of antigen D on RBC. If the agglutination occurs that indicates Rh positive or if the agglutination does not occur that indicates Rh negative.

Question 7

Answer is E ( All the above)

RBC, WBC, and Platelets are formed elements. The lymphocytes are also formed elements belongs to WBC.
