<span>a. natural monopoly
</span><span>A common example of a natural monopoly is electricity service. To provide it, workers must build power stations and power lines. The company must connect each customer's home or business to the system of lines and stations. The costs are very high. If more than one company offered electrical service to an area, that means more power stations and lines that would cross each other. It is more efficient, safer, and less costly to allow one company to control the electricity service to an area. With more customers on the same power grid, or system of electricity flow and equipment, the costs are spread out more and so prices are lower.</span>
The correct answer is the doll
Hypotheses, dependent and independent variables form a set of tools that help us to create theories about natural phenomena.
The process for investigating a particular phenomenon in nature usually involves three levels. In the first level, observation of facts, phenomena, behaviors and activities takes place; at the second level, we have the hypotheses and finally, at the third level, theories, valid and sustainable hypotheses (those that have been tested) arise.
Independent Variable:
these variables influence, affect or determine other variables.
it is a determining factor, condition or cause for a given result, effect or consequence.
it is the factor manipulated by the researcher in order to determine the relationship of the factor with the observed phenomenon, to see what influence it has on a possible result.
