Can someone give a explanation on what is Natural Selection? 15 POINTS AWARDED!

Answers

Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success. [A genotype is a group of organisms sharing a specific genetic makeup.]

It is dangerous if directly inhaled
It is not a very abundant energy source

Answers

Answer: Still adds carbon dioxide to the atmosphere, Can have gas leaks which are a safety hazard because it is colorless and odorless, It is dangerous if directly inhaled

Explanation:

Final answer:

Natural gas, despite being the cleanest of the fossil fuels, has some associated problems. It still adds carbon dioxide to the atmosphere, can have gas leaks which are a safety hazard, and is dangerous if directly inhaled.

Explanation:

Natural gas, while considered the cleanest of the fossil fuels, still has some problems associated with its use:

It still adds carbon dioxide to the atmosphere: Like other fossil fuels, natural gas releases carbon dioxide when burned, contributing to climate change.
It can have gas leaks which are a safety hazard: Natural gas is colorless and odorless, making it difficult to detect. Leaks can lead to fire or explosions, posing a safety risk.
It is dangerous if directly inhaled: Inhaling natural gas can lead to asphyxiation, which can be harmful or even fatal.
