Yes, it is the correct answer.
Pyrodictium is a genus of submarine hyperthermophilic archaea whose optimal growth temperature ranges is 80 to 105°C.

Ureaplasma exhibits respiratory metabolism.

Yes, both are true.
Site for oxidative phosphorylation in prokaryotic cells is cell membrane.
Cytoplasmic ribosome size of prokaryotic cells is 70S. Ribosomal subunits are 50S and 30S.

Yes, it is correct. Voges–Proskauer test is used to detect acetoin in bacterial broth culture. The test is performed by adding alpha-naphthol and potassium hydroxide to the Voges-Proskauer broth, which has been inoculated with bacteria. A cherry red colour indicates a positive result, while a yellow-brown colour indicates a negative result.
Both Escherichia coli and Proteus mirabilis give negative Voges–Proskauer test.

Yes, it is the correct answer. Amoxicillin acts by inhibiting bacterial cell wall synthesis.

Yes, it is the correct answer. Rhizobium is a nitrogen-fixing bacteria living in a symbiotic relationship with legumes.
