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.
