Hydropower can be harnessed from flowing and falling water. Water stored behind dams and at a height has a lot of potential energy which is converted into mechanical and electrical energy.This water is released gradually and is made to fall under the force of gravity and drive hydraulic turbines and electrical generators.
Hydropower is also another indirect form of using solar energy. Hydropower has great potential as a supplier of electricity but environmental constraints limit such a development as the generation of electricity by hydroelectric power plants result in pollution and massive ecological disruptions such as land flooding, siltation, eutrophication and adverse effects on flora and fauna.
Smaller dams and reservoirs cause less damage but cannot exploit the full potential of this energy resource. Planning environmental impact assessment and construction of a hydroelectric power plant takes many years and the high initial capital investments are also limiting factors in the development of hydropower.
The development cost of hydroelectric power plants can be reduced by developing low cost turbines and generators, involving public participation in the development and operation of the project and using efficient environmental friendly technologies.
The diagram given here describes the process - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
The alveolus or alveoli are tiny air sacs which is a hollow cup-shaped cavity in the lung parenchyma. It functions as the respiratory unit. It helps in gaseous exchange to and from the lungs.
The gaseous exchange takes place with these sacs.
Diffusion is the process that takes place in this exchange
In this process, oxygen moves from a high concentration area to a low concentration that is alveoli to blood capillaries and then circulates to various cells.
In the case of carbon dioxide, it reaches near the blood capillaries near the alveoli where it diffuses into the lungs through alveoli.
Thus, the correct description is - The alveolus is a part of the lung and assists with gas exchange. The goal is to get gases into and out of the cells, so they enter our body, go to our lungs and then diffuse into our blood and travel to our cells through our circulatory system.
