Question

which statement(s) among a - d is false regarding sulfur - oxidizing prokaryotes? o they are common in marine environments, where concentrations of sulfur compounds are higher. o they are lithotrophs. o the sulfur compounds utilized by them serve as electron donors to their electron transport system. o their metabolism often results in very acidic external environments. o none of a - d are false, they are all true statements.

Explanation:

• Sulfur - oxidizing prokaryotes are lithotrophs that use sulfur - compounds as electron donors in their electron - transport system. They are common in marine environments with high sulfur - compound concentrations. Their metabolism can lead to acidic external environments due to the production of sulfuric acid as a by - product.

Answer:

None of A - D are false, they are all true statements.
