Question: Which of these are produced in response to foreign substances called antigens?

Answer: Antibodies are produced in response to substances called antigens. When an alien substance enters the body, the immune system is able to recognize it as foreign because molecules on the surface of the antigen differ from those found in the body. As antibodies circulate, they neutralize antigens by attaching to them.

Question: Who was the first person to describe the blood parasite responsible for malaria and to recognize it as the cause of that disease?

A doctor must be a traveller.… Knowledge is experience.”

Question: What causes the blood disease thalassemia?
