🗑
antibiotics   Bacterial diseases can be treated with  
🗑
antibiotics   are medicines that stop the growth and reproduction of bacteria

virus   is a strand of DNA or RNA surrounded by a layer of protein that can infect and replicate in a host cell.  
🗑
virus   They are between 20-100 times smaller than bacteria  
🗑
host cell   9. Viruses are not considered living things; they can replicate but must rely on a living organism to do so. The cell that the virus attaches to is called the ______.  
🗑
viral   Antibiotics do not work against _________infections  
🗑
communicable diseases   are also call infectious diseases  
🗑
pathogens   Communicable diseases are caused by _________________ that can be transmitted from one person to another.

🗑
vector   a disease carrying organism that does not develop the disease.

antibiotics   Used to treat and possibly cure BACTERIAL infections. Ineffective against viral diseases
