Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.
Explanation:
Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.
Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.
Disadvantage: It is very costly and takes more space for installation
Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.
