Answer:
a)Viruses, like the common cold or influenza are not alive and must invade living cells to grow. The body’s own immune system must fight off the virus or let it run its course. Viral infections are usually accompanied by multiple symptoms such as a sore throat, runny nose, congestion, vomiting and diarrhea.
Bacteria are living organisms and can be found everywhere. There are times when the body’s immune system may not be able to fight off a bacterial infection. Antibiotics work to kill the bacteria by stopping its growth. Bacterial infections often go together with pain, aches, or sore areas of the body.
