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. Neither can replicate independently. Neither can replicate independently. Streptococcus pneumoniae can replicate independently, but SARS-CoV-1 requires a host cell to replicate. Streptococcus pneumoniae can replicate independently, but SARS-CoV-1 requires a host cell to replicate. Both can replicate independently.

Answer 1

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

To clarify:

- **SARS-CoV-1** is a virus; viruses require a host cell to replicate and cannot replicate independently.
- **Streptococcus pneumoniae** is a bacterium; bacteria can replicate independently through cellular division.

Therefore, the other options provided are not accurate based on these characteristics.
