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.

In artificial selection, humans provide the selective pressure for species to change and shape the evolution of various breeds.
asambeis [7]
The environment provides the selective pressure in natural selection. Artificial Selection  is a type of choice in which people effectively pick which characteristics ought to be passed onto posterity. People have utilized particular rearing some time before Darwin's Postulates and the disclosure of hereditary qualities. It is the rearing of plants and creatures to deliver attractive qualities. Living beings with the coveted characteristics, for example, size or taste, are misleadingly mated or cross-pollinated with creatures with comparable wanted attributes.

How do genetic modification variations likely to differ from genetic sexual reproduction variations
ololo11 [35]

Answer:

The  genetic modification variations result in the change in the genome of the organism. In this case, the variations result in expression of a trait in different form than usual. These variations results in genetic mutation, which can be inherited from one generation to another.

In sexual reproduction, the genome of the organism is not altered. In this only an exchange between the maternal and the maternal alleles takes place, these changes does not result in mutations.

You’re welcome :)

andrew11 [14]

Answer:

Freon

Explanation:

<em>Freon is a trademark name for halocarbon (specifically, fluorocabon) products that once served (and still serve in some cases) as refrigerants. They are no longer utilized as refrigerants due to their negative effects on the environment and the ecosystem in general.</em>

<em>In addition to being used as refrigerants, freons are also used as aerosol propellants in cosmetics and household sprays.</em>
