Question

question 1
according to the presentation, infectious diseases are caused by:
○ genetic and lifestyle factors
○ only inherited traits
○ microscopic germs
○ environmental factors

Explanation:

Infectious diseases are caused by microscopic germs (like bacteria, viruses, fungi, etc.) that can invade the body. Genetic/lifestyle/environmental factors or only inherited traits are not the primary causes of infectious diseases (genetic factors relate more to genetic disorders, lifestyle to non - infectious like heart disease, environment to some exposures but not infectious disease causation in the primary sense). So the correct option is about microscopic germs.

Answer:

C. Microscopic germs (assuming the options are labeled A: Genetic and Lifestyle Factors, B: Only inherited traits, C: Microscopic germs, D: Environmental Factors)
