Gills would be the most common sense answer. I took the test and it was correct.
Answer:
B. store excess carbon underground
Explanation:
The fossil fuels have been formed on the basis of organisms that have died, mostly producers. These organisms have carbon stored in them. As they died and got covered by sediments, the carbon has been stored in the lithosphere. Since more and more sediments have been covering the stored carbon, it has been isolated and stored into the lithosphere for tens or even hundreds of millions of years, thus contributing to lowering the amount of carbon in the atmosphere for quite some time, and removing it from its natural cycle.
In general, coding regions are more likely to have the same sequence. It is more likely to produce a non-functional gene product (protein).
Non-coding mutations are free to mutate because it has no protein product, and are less likely to affect phenotype. They are neutral mutations. Different mutations can be differentiated even when different groups have the same coding sequence.
