Which term describes Salmonella and E. coli?

• A. Virus
• B. Harmful Bacteria
• C. Algae
• D. Amoebas

Answer: (B)

Salmonella and E. coli are bacteria, tiny single-celled living organisms. Bacteria are prokaryotes, meaning they lack a true nucleus. Some bacteria are harmless, but many strains can cause illness, so these particular ones are described as harmful bacteria. They’re not viruses, which need a host cell to reproduce; they’re not algae, which are plant-like and usually live in water and photosynthesize; and they’re not amoebas, which are a different kind of single-celled organism that moves with extensions called pseudopods. So, the best term for them is harmful bacteria.
