Answer:

Option (C)

Explanation:

A star is an astronomical body that is located at a large distance from the earth. They appear to be shinning in the sky. The process of nuclear fusion takes place in the stars, where the nuclei of two smaller and lighter atoms are combined together in order to form a nucleus of heavier atoms. Here, the hydrogen atoms are combined to form a helium atom, and during this process of fusion, a significantly large amount of energy is released.

Thus, stars produce a large amount of energy by forming helium from the combination of hydrogen in its core.

Hence, the correct answer is option (C).

Answer:C. Creating helium from hydrogen in its core

Explanation: Stars produce energy majorly by nuclear fusion. The process of creating helium by merging hydrogen atoms to produce deuterium which in turn is converted to helium.

Describe three clean coal technologies and how they can mitigate the environmental impacts of coal. Explain how they work and pr
Andrej [43]

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.

Why is weeding flower beds so imprortant?
Maurinko [17]

Answer:

It's important to rid your garden of weeds because they rob your soil and your plants of important nutrients and water.

Jack was sick with a cold and fever. the doctor prescribed him erythromycin, an antibiotic. analyzing the process of translation
KatRina [158]

Answer:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
