<h2><u>Answer</u> : </h2>
Proteins are basic nutrients comprising biomolecules, which are made up of long chains of Amino acids.
They have various functions in our body :
- they make up our hair, nails, bones etc
- they helps in recovery of damaged tissues (therefore known as body - building food)
- the structure and functions of protein depends on base sequence of nucleotides in the DNA coding for that specific protein.
<span>The roots of plants are able to self-regulate the amount of water they take in. Therefore, by adding this amount of water, Stela is insuring that the plant will have as much water as it needs to grow. </span>
The correct answer is "reefs".
Shallow-marine environments are considered to be an area among the shore and deeper water, along with a reef wall or a shelf break. This surroundings is characterized by means of oceanic, geological and organic conditions, as described underneath.
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.
