Process:  - Bacteria enter the body - Bacteria start to divide and grow - The uncontrolled growth takes away resources from other cells - Other cells cannot function properly - We feel unwell - The growth and division of bacteria produce toxins - Toxins harm the body - The body tries to react to the toxins - The body&#x27;s natural defenses can sometimes cause us to feel unwell.  Perturbation hypothesis: suppose more frequent hand washing happens, how will it affect more cells cannot function properly.  Does the supposed perturbation have an effect (direct or indirect) on the process?
The answer to this question is:
yes
