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.
Since this is movement that is occurring against the natural movement from high to low concentration, this is Active transport.
The option C.
A sea sponge is what mimics a synthetic sponge
The largest cell in the human body is the ovum, the female sex cell. The largest cell in the world is an ostrich’s egg.
