How do bacteria clean the environment
Digests organic waste and nitrates to purify water supplies
How can bacteria enter our bodies

Antigen
Any substance that causes the body to make an immune response against that substance.
Capsid
Protein surrounding the virus
Lytic infection
Produces an active infection
Vaccine
Small piece or weakened version of virus,that trigger the immune system to make memory cells for exposure
Difference between gram positive and negative?
Gram-negative bacteria are surrounded by a thin peptidoglycan cell wall, which itself is surrounded by an outer membrane, Gram-positive bacteria lack an outer membrane
Hygiene
Cleanliness like washing hands, showers, etc.
Can viral infections be treated with antibiotics
NO, virus can cause secondary infections like pneumonia and sinus infection
