Answer:
I think that the fossil is a carbon fossil
Explanation:
They preserve life in fine detail, including the soft tissue of plants and animals.
Contaminated water such as polluted water can sometimes cause an explosion of new plant growth by providing necessary nutrients and food and at other times it can kill or harm plants such as by raising or lowering acidity. Plants need at least good levels of potassium, nitrogen and phosphorus for healthy growth and by corollary, biodiversity. I believe that water which contains these elements, even if it be contaminated with the right contaminants will aid in biodiversity by enhancing growth. On the other hand, if there is too much salt, for example in the water it will prevent growth and inhibit photosynthesis.

Answer:
Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.
Explanation:
Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.
In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
