Question

recognizing pathogens and symptoms of illness
what are two main types of disease - causing pathogens?
bacteria and viruses
communicable and noncommunicable
ebola and measles
infectious and noninfectious

Explanation:

Pathogens are disease - causing agents. Bacteria are single - celled microorganisms that can cause infections. Viruses are non - cellular entities that need a host cell to replicate and can also cause diseases. Communicable and non - communicable refer to the nature of diseases (whether they can be spread or not), not the pathogens. Ebola and measles are specific diseases caused by pathogens (Ebola virus and measles virus respectively). Infectious and non - infectious are related to the ability of a disease to spread, not the types of pathogens.

Answer:

bacteria and viruses
