What effect would overfishing most likely have on a population of fish in a lake? A. cause a gene flow to occur in the populatio
n B. create a bottleneck effect, reducing genetic diversity C. create a founder effect, restricting genetic variation D. increase the chances of mating between nonrelated partners E. favor the process of stabilizing selection in the population
Overfishing would result in an bottleneck effect as large number of fish is removed from a population of fishes. The size of the population has an larger effect on the amount of genetic diversity. Larger the population greater the genetic diversity.Due to overfishing, population would become smaller resulting in reducing genetic diversity. So the answer is B.
Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.
