Question

SARS is a respiratory illness caused by SARS-CoV-1, a coronavirus. It belongs to the same family of viruses that cause common colds. Streptococcus pneumoniae is a bacterium that causes pneumonia. Pneumonia is an illness that causes fluid buildup in the lungs. Which of the following statements correctly identifies the characteristics of SARS-CoV-1 and Streptococcus pneumoniae? (1 point) Responses SARS-CoV-1 can replicate independently, but Streptococcus pneumoniae requires a host cell to replicate. SARS-CoV-1 can replicate independently, but Streptococcus pneumoniae requires a host cell to replicate. Both can replicate independently. Both can replicate independently. Neither can replicate independently. Neither can replicate independently. Streptococcus pneumoniae can replicate independently, but SARS-CoV-1 requires a host cell to replicate.

Answer 1

The correct statement is: **SARS-CoV-1 requires a host cell to replicate, but Streptococcus pneumoniae can replicate independently.**

This means that SARS-CoV-1, being a virus, cannot replicate on its own and must infect a host cell to reproduce. In contrast, Streptococcus pneumoniae is a bacterium that can grow and replicate independently in suitable environments. Therefore, the following option aligns with the understanding of their replication capabilities:

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