I am new at this but i want to make sure i know what i am talking about I have researched this but i haven't gotten a straight answer 1. When you get sick(common cold/virus) what happens? Does virus go into each cell and take its nutrients. Then after that does it keep on spreading and then your body tries to kill it and then you get fever and runny stuffy nose. 2. When you take antibiotics how does it kill bacteria? and are there different types of bacteria so wouldn't they be the same as viruses Also i remember long ago i heard one of them was living is that true or not.
