Question

Microbes are important in human culture and health in many ways, serving to ferment foods and  treat sewage, and to produce fuel, enzymes, and other bioactive compounds. Microbes are  essential tools in biology as model organisms and have been put to use in biological warfare and  bioterrorism. Microbes are a vital component of fertile soil. In the human body, microorganisms  make up the human microbiota, including the essential gut flora. The pathogens responsible for  many infectious diseases are microbes and as such are the target of hygiene measures. Microorganisms are the causative agents (pathogens) in many infectious diseases. The organisms  involved include pathogenic bacteria, causing diseases such as plague, tuberculosis and anthrax;  protozoan parasites, causing diseases such as malaria, sleeping sickness, dysentery and  toxoplasmosis; and also fungi causing diseases such as ringworm, candidiasis or histoplasmosis.  However, other diseases such as influenza, yellow fever or AIDS are caused by pathogenic  viruses, which are not usually classified as living organisms and are not, therefore,  microorganisms by the strict definition. Numerous microbial pathogens are capable of sexual  processes that appear to facilitate their survival in their infected host. 1. Ascaris worm lives in which part of human body?
