Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:
1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.
2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.
3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.
An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.
Answer:
Aldosterone release is stimulated by a decrease in blood sodium levels, blood volume, or blood pressure, or an increase in blood potassium levels. It also prevents the loss of Na+ from sweat, saliva, and gastric juice.
Explanation:
How many drops of caffeine she drops on the worm is the manipulated variable.
In an experiment, the independent variable is a manipulated variable. Due to the fact that you may alter it, it is termed the "manipulated" one. In other words, you can choose in advance whether to raise it or lower it. Only one variable should be changed at a time throughout an experiment.
The Independent variable is Caffeine's impact. the production and use of nitrogen fertilizers, as well as the burning of fossil fuels in autos, power plants, and industries, are dependent variables that are local in scope. the heart rate of the worm is the responding variable in this experiment.
When an earthworm is given a stimulant like caffeine, its heart rate rises. Does coffee make an earthworm's heart beat faster? is the research topic upon which the experiment is based. The effect of coffee is the independent variable in this research question, and the response it causes is a change in heart rate (the dependent variable) This brings us to the following theory: "If an earthworm is given a stimulant like caffeine, then its heart rate accelerates."
