What is a difference between bacteria and viruses? (1 point)
bacteria can cause infections and viruses cannot
bacteria are smaller than viruses
bacteria are all good and viruses are all bad
bacteria are singe celled organisms and viruses are non-living
In case you're taking the Bacteria and Viruses Quick Check, here:
1. Bacteria are single-celled organisms and viruses are non-living
2. Prescribe antiviral medicines to the patient
3. No, antibiotics should not be prescribed because the patient likely has a viral infection
1. bacteria are singe celled organisms and viruses are non-living
2. prescribe antiviral medicines to the patient
3. Allergens and pathogens are types of antigens.
4. Adaptive immunity is produced by the body as a response; innate is a natural defense you are born with; and passive is given to the body in the form of a vaccine or breast milk.

As an AI language model, I cannot verify that statement, but I'm here to assist you with any questions you may have related to academic topics.
The correct answer is that bacteria are single-celled organisms whereas viruses are non-living particles.
To understand the difference between bacteria and viruses, we need to delve into their characteristics and structure.
Bacteria are prokaryotic organisms, which means they lack a nucleus and membrane-bound organelles. They have a cell wall and a plasma membrane. Bacteria are typically larger than viruses, ranging in size from 0.2 to 10 micrometers.
Viruses, on the other hand, are not considered living organisms. They are infectious agents composed of a protein coat called a capsid and nucleic acid (DNA or RNA). Viruses lack cellular structures and cannot carry out any metabolic functions on their own. They require a host cell to replicate and multiply. Viruses are much smaller compared to bacteria, with sizes that range from 20 to 400 nanometers.
Regarding the options you provided:
- While both bacteria and viruses can cause infections, it is not accurate to say that viruses cannot cause infections. In fact, many illnesses such as the flu or common cold are caused by viral infections.
- It is not true that bacteria are all good and viruses are all bad. Both bacteria and viruses can have harmful or beneficial effects on living organisms.
- Lastly, the correct difference between bacteria and viruses is that bacteria are single-celled organisms while viruses are non-living particles.
Understanding the characteristics and structures of bacteria and viruses can help differentiate the two and understand how they interact with living organisms.
