Worked Solution & Example Answer:Allergies are the result of an immune response - HSC - SSCE Biology - Question 13 - 2006 - Paper 1
Step 1
What triggers this response?
Answer
Allergies are triggered by exposure to substances known as antigens. These are typically harmless substances that the immune system mistakenly identifies as threats. When an individual encounters an antigen, the immune system reacts by producing antibodies, which can lead to allergic symptoms. Therefore, the correct answer is (A) Antigens.
