Define the roles of observations and hypothesis in science
BARSIC [14]

Answer:

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing

The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions

Why does the damage of the nervous system cause paralysis of the body?
Shtirlitz [24]
Paralysis is most often caused by damage in the nervous system, especially the spinal cord. The nervous system is what give signals to the different parts of our body so that if it is damaged signals and messages could not be transported. If the central nervous system is damaged, paralysis frequently affects the movement of a limb as a whole, not the individual muscles.
