A cause for infection is pathogens entering the body. This is either to a disease that's being transferred from one being to another, or through toxins, wounds, and similar things. Most commonly, when fighting the infection, the body produces white blood cells to combat the infection, which in combination with medication usually defeats the infection.
Hey!
A physical hazard is a danger (hazard) that can occur physically. Let's check the answer choices.
A: bacteria, this is not a physical, it's a biological hazard.
B: viruses, this is also a biological hazard
C: Hair, it's not likely to cause any physical hazard, we may sometimes eat hair without even knowing it.
D: pesticide, this is actually a physical hazard, because if it stays in contact with your skin for a long period of time, it can cause irritation and damage. This would be your answer.
Thanks!

Super glue does not last long on the skin. It will eventually dissolve in a few days naturally. If you would like to speed up the process, you can rinse off the area with warm water. However, if the glue does not come off, you will develop a rash and most likely will have to see the doctor.
