Question

In three to four sentences, describe how viruses and bacteria affect the human body.(2 points)

Answer 1

Viruses and bacteria are microorganisms that can significantly impact the human body, often leading to disease. Bacteria can be beneficial, aiding in digestion and immune function, but pathogenic bacteria can cause infections, leading to symptoms like fever and inflammation. Viruses invade host cells to replicate, often disrupting normal cellular functions, which can result in illnesses ranging from mild colds to severe diseases like influenza or COVID-19. The body responds to these invaders through the immune system, which may include inflammation and the production of antibodies to combat the infection.
