Answer:

option (a).

Explanation:

Biomolecules are the important organic molecules that plays an important role in the living organism. Four important biomolecules are carbohydrate, proteins, lipids and nucleic acids.

Lipids consist of fatty acids that contain the hydrophobic hydrocarbon tail and the hydrophilic head that contains the carboxylic acids. Lipids can be easily tested by dissolving them in water. Lipids are insoluble in water and starts floating on the surface of water. Lipids are easily soluble in organic solvents. Some lipids may also form micelles in water.

Thus, the correct answer is option (a).

To trace our maternal lineage, we observe mutations that have accumulated in our mitochondrial dna (mtdna). in the dna isolation
Sergio [31]
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.
