Answer:
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Explanation:
- Fossil fuels such as coal, petroleum and natural gas are produced and stored in the geosphere. i.e. the part of the Earth that includes the Earth's interior, landforms, rocks and minerals.
- Fossil fuels, extracted from the geosphere are burned to generate energy.
- Combustion of fossil fuels releases the stored carbon into the atmosphere in the form of carbon dioxide.
Answer:
The mutation will become more common in offspring and increase the genetic variability in the gene pool.
Explanation:
If the mutation is beneficial to the organism and this organism breeds its offspring may carry this gene, if it´s really beneficial and for example makes an organism to have more access to females the mutation may spread faster.
The only way for a mutation to spread to other organisms is reproduction (eukaryotes)
A mutation may also spread to other organisms in prokaryotes in which bacteria may take plasmids (DNA fragments) from the environment.
