Sometimes I’ve been sick and a doctor has given me medicine. Other times I’ve been sick but a doctor has not given me medicine. I think this is because of the type of illness I had.
Infections can be spread easily through saliva and mucus droplets.
You should stay home when you’re sick so you do not spread the bacteria or virus to other people.
Washing your hands kills bacteria and viruses that may cause you to get illnesses like salmonella.
After Video
How do you know if something is living or nonliving?ANSWERLiving things must take in nutrients, have genetic material, and reproduce.
Bacteria and viruses can spread easily by touching.
You can find bacteria everywhere! They are in the soil, on your skin, inside your body, and even in your poop! Bacteria grow together and are most often found in groups, called colonies.
Antibiotics only kill bacteria and do not work against viruses.
Viruses do not take in nutrients and do not reproduce on their own. They need a host cell.
Viruses hijack cells to make copies of themselves and then burst out of the cell. The copies infect other cells.
