Text Solution

AI Generated Solution

The correct Answer is:
To solve the problem of matching items from Column I with their corresponding items in Column II, we will analyze each item in Column I and find the correct match in Column II based on the information provided. ### Step-by-Step Solution: 1. **Virus Free Plant**: - The method used to create virus-free plants is through **meristem culture**, specifically using the **shoot apex**. - **Match**: I (Virus free plant) → C (Shoot apex) 2. **Biofertilizer**: - A common biofertilizer is **Rhizobium**, which is a nitrogen-fixing bacterium. - **Match**: II (Biofertilizer) → A (Rhizobium) 3. **Bt Cotton**: - Bt Cotton is genetically modified to produce **Cry genes**, which are toxic to certain pests. - **Match**: III (Bt Cotton) → B (Cry gene) 4. **Humulin**: - Humulin is a form of insulin used to treat diabetes, specifically it is **regular insulin**. - **Match**: IV (Humulin) → D (Diabetes) ### Final Matches: - I → C - II → A - III → B - IV → D ### Summary of Matches: - I. Virus free plant → C. Shoot apex - II. Biofertilizer → A. Rhizobium - III. Bt cotton → B. Cry gene - IV. Humulin → D. Diabetes
