Biology Practice: Diseases - Causes & Control (Mock Test 4 - Expert Logic & Experimental Setup)
1. In a clinical trial, a patient's serum is mixed with a specific viral antigen. Agglutination (clumping) is observed. What does this expert observation logically conclude?
2. A researcher is testing a new "Bactericidal" agent. How does this agent differ logically from a "Bacteriostatic" agent?
3. Why is "Oral Rehydration Solution" (ORS) used in Cholera treatment rather than just plain water?
4. An expert analyzes the "Step-ladder" fever pattern in a patient. Which diagnostic test is logically the next step to confirm the disease?
5. "Antiseptics" like tincture of iodine are applied to wounds, while "Disinfectants" are used on floors. Why can't disinfectants be used on wounds?
6. A patient is treated with "Penicillin." Which part of the bacterial structure is primarily affected by this antibiotic?
7. Why is the "Anopheles" mosquito called a "Biological Vector" while a housefly is called a "Mechanical Vector"?
8. In the "Eradication of Smallpox," which logical factor contributed most to global success?
9. A doctor prescribes "Sulphadrugs" for a patient. These drugs are logically classified as:
10. During an epidemic of "Bubonic Plague," why was it critical to control the rat population?
20. "Phagocytosis" is a cellular mechanism where WBCs:
