So this is a multi -part question, we'll answer it one by one.
00:03
The first part is what are the three parts of hair? hair is made up of three parts called the follicle, the root and the shaft.
00:16
The second question, based on hair, can a person be identified? so the answer is no.
00:23
So same hair type.
00:26
So hair types on microscopy may be similar.
00:33
For two individuals, however, dna sampling from the hair only identifies every individual separately.
00:41
So hair type identification with microscopy cannot differentiate individual person.
00:48
So the answer is no.
00:51
So third question.
00:53
Natural fibers are secreted by various secretions in animals and also plants have natural fibers in their cell wall components.
01:02
So the components of animal fibers include wool, silk and also hair.
01:12
They are all natural fibers.
01:15
So for example, in plants, the natural fibers includes cotton, hemp.
01:24
So these are the five different natural fibers.
01:28
So let's answer the next question.
01:31
The fibers that are manufactured under laboratory process or manufacturing units, is called as manufactured fibers or m fibers or man -made fibers.
01:42
These fibers include nylon, rayon, and polyester, to name a few...
