The cuticle and medulla can be important for distinguishing between hairs of different , but often does not lend much important information to the differentiation between hairs from different .

Species / People.

Explanation:

The hairs are made up of three distinct layers which are cuticle, medulla and cortex. Cuticle is the outer layer in the medulla is located at the center. The cuticle and medulla can help in distinguishing hairs among different species since their properties are much different but they do not offer too much information for distinguishing hairs between to organism from the same species like two people.

I hope this answer helps.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)
