Answer 1

The correct statement is:

Streptococcus pneumoniae can replicate independently, but SARS-CoV-1 requires a host cell to replicate.

Explanation:

• Streptococcus pneumoniae is a bacterium, which means it can reproduce on its own and does not require a host organism for replication.
• SARS-CoV-1, on the other hand, is a virus. Viruses cannot replicate independently; they require a host cell to reproduce.
