 2. Explanation of the statements:
 
     ● Statement I: No virus can survive in ocean waters.  
           ○ Incorrect.
           ○ Viruses are abundant in ocean waters and play a crucial role in marine ecosystems.
           ○ Marine viruses infect a variety of organisms, including bacteria and plankton.
           ○ They contribute to nutrient cycling and influence the population dynamics of marine life.
 
     ● Statement II: No virus can infect bacteria.  
           ○ Incorrect.
           ○ Bacteriophages are viruses that specifically infect bacteria.
           ○ They are one of the most common and diverse entities in the biosphere.
           ○ Bacteriophages play a significant role in controlling bacterial populations and transferring genetic material between bacteria.
 
     ● Statement III: No virus can change the cellular "transcriptional activity" in host cells.  
           ○ Incorrect.
           ○ Many viruses can alter the transcriptional activity of host cells to facilitate their replication.
           ○ Viruses can hijack the host's cellular machinery to produce viral proteins.
           ○ This alteration can lead to changes in the host cell's normal functions and contribute to disease processes.
