Practice questions testing deep understanding of immunity, HIV/AIDS, and cancer.
Q1. A person is bitten by a highly venomous snake and is rushed to the hospital. The doctor immediately injects them with "anti-venom." Is this an example of active immunity or passive immunity? Justify your answer biologically.
Q2. The HIV virus that causes AIDS does not actually kill humans directly. Instead, people with AIDS usually die from common, normally harmless infections like simple pneumonia or mild fungal infections. Explain the biological mechanism of the HIV virus that makes this happen.
Q3. Assertion (A): Benign tumors are generally considered less dangerous than malignant tumors. Reason (R): Benign tumors are enclosed in a connective tissue capsule and remain strictly confined to their original location. Malignant tumors exhibit "metastasis," breaking away and invading other organs through the bloodstream to form lethal secondary tumors.
