                  This question was attempted by many candidates and their  performance was impressive,  except in question (a)(ii) and b(ii). Candidates failed to mention  types of body immunity, they mentioned  antibodies and innoculation instead of natural acquired immunity and artificial passive immunity.  The expected answers to  part b(ii) were as follows: 
                     First Aids Treatment of  poison victim 
                      - Place on his  side/recovery position;  
                      - If unconscious look  around for clues of what the victim ingested/interview the victim if conscious.  
                      - If ingested substance is  corrosive give large quantities of water/milk;  
                      - If non-corrosive induce vomiting  by tickling the back of victims' throat/give the victim a glass of solution of  common salt and water  
                      - Consult a doctor   |
