The correct Answer is:
To solve the question regarding the statements about bacteria, we will analyze each statement one by one and determine their correctness. ### Step-by-Step Solution: 1. **Statement 1: They are the sole members of the kingdom Monera.** - This statement is **correct**. Bacteria are indeed the only members of the kingdom Monera, which is a classification that includes prokaryotic organisms. 2. **Statement 2: Cannot live in snow and deep oceans.** - This statement is **incorrect**. Many bacteria can survive in extreme environments, including snow and deep oceans. For example, the bacterium *Pseudomonas syringae* can thrive in snowy conditions. 3. **Statement 3: No bacteria live in or on the other organisms as parasites.** - This statement is **incorrect**. Many bacteria do live as parasites on or in other organisms. For instance, bacteria like *Streptococcus* can be pathogenic and live in humans. 4. **Statement 4: Have simple structure and complex behavior.** - This statement is **correct**. Bacteria are generally unicellular and have a simple cellular structure, but they can exhibit complex behaviors such as communication and biofilm formation. ### Conclusion: Based on the analysis: - **Correct Statements:** 1 and 4 - **Incorrect Statements:** 2 and 3 Thus, the correct option for bacteria is that they are the sole members of the kingdom Monera and have a simple structure with complex behavior. ### Final Answer: The correct option is **1 and 4**. ---
