Question

Becoming exposed to or infected with an infectious microbe does not necessarily mean developing noticeable disease. Explain.

Answer 1

Our body possess many white blood cells which are part of our immunity and they help in fighting of diseases. Every disease has a particular incubation period. If within that time, W.B.C fights off the microbe, the disease does not develop.
Sometimes, there exist some diseases that damage body internally but don't show any changes which are noticeable e.g. diabetes.

Answer 2

Answer:

Infected with a microbe does not mean developing a disease because an infectious microbe is able to cause a disease only if the immune system of the person is weak and a person with strong immune system normally fights off microbes.

We have cells which are specialised to kill the pathogenic microbes. These cells are active when infecting microbes enter the body and if they are successful in removing the pathogen, we remain disease-free. So, even if we are exposed to infectious microbes, the person will not catch the disease.
