In the coding region, natural selection tends to eliminate all of the mutations because of the high importance these regions have. The coding region contains genes that synthesize proteins and the changes in the DNA sequence can have devastating effects on the cell. Therefore, there are very few differences in the sequences of coding regions that can help us trace the lineage.
On the other hand, in the non-coding regions, the mutations often accumulate because they have little effect on the cell and the adaptive value of the organism. This enables us to trace up the lineage by comparing the sequences and seeing the differences in the sequences.
It is d because the law was passed around 1976 I am not sure but this is the best estimate
Although now it causes more harm than good because it doesn't really have a purpose, it is believed it once was used for humans to digest bone.
Answer: it would block your airways to stop you from breathing
Explanation:
its easy just think if your noise was stuffy it would be hard to breath did a 6th grader really have to tell you that
First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst. hope this helps :)
