The herpes virus infects the humans to cause chickenpox disease. The virus during its stage of causing infection, it spreads through the epidermal cells by infecting them. This causes the typical rash on skin that is seen in chickenpox. The virus then enters that sensory nerves present on the ski and travels along the length of the neurons to the sensory dorsal-root ganglia adjacent to the spinal cord. Here the virus stays in an inactive stage.
Answer:
A. True
Explanation:
We continuously use drugs and antibiotics against the micro organisms. In the course of time, some microbes may develop resistance against these antibiotics by bringing changes or modifications in their structures. Those which become resistant, survive the selective pressure and hence selected by the nature. Hence developing drug resistance by microbes is also an example of natural selection.
Similarly herbicides and pesticides resistance developed in weeds and pests respectively after prolonged use of herbicide and pesticide is also an example of natural selection which supports the process of evolution.
