How Do Bacteria and Viruses Differ from Each Other

Question

Examlex · Accepted Answer

The Answer is A. Bacteria are organisms capable of living and reproducing on their own. Some can be harmless and actually beneficial such as those that are found in the healthy intestines of humans or in yogurt. Bacteria that cause diseases are called pathogens, which harm the body by attacking tissues directly or by producing poisonous substances called toxins.
B. Viruses are unable to survive or reproduce without invading another cell. Viruses enter a living host cell and use the reproductive capacity of that cell for its own replication. Usually the body recognizes when a virus is present and activates the immune system to attack and destroy in. Some type of viruses, when not destroyed, can remain inactive in the body for long periods of time without causing any problems; however, they remain integrated within the genetic material of the cell and are capable of replicating when triggered to do. An example of this is the varicella zoster virus that causes chickenpox in children, but can cause herpes zoster in adults.
