Reagents are specific chemicals used to test for the presence of particular macromolecules. For example, Benedict's reagent can detect reducing sugars like glucose by changing color when the sugar is present. Iodine solution can detect starch by turning blue-black in the presence of this polysaccharide. By using different reagents, we can identify the types of macromolecules present in a sample based on their specific chemical reactions.

They could be useful while determining the valency of atoms and the structures of chemical bonding in plausible ways.
Alkaloidal reagents can be useful for detecting or quantifying alkaloids in samples, which can have pharmaceutical, medicinal, or toxicological implications. They can also help identify the presence of specific alkaloids in plants or other materials, aiding in research and quality control processes.
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
A compass is still useful for determining direction because it points towards the magnetic north pole, providing a consistent reference point that helps in navigation. Even though the magnetic north pole and geographic north pole are not aligned, the difference can be accounted for using magnetic declination adjustments.
