Hairs, which are composed primarily of the protein keratin, can be defined as slender outgrowths of the skin of mammals. Each species of animal/human possesses hair with characteristic length, color, shape, root appearance, and internal microscopic features that distinguish one animal from another.
In this lab we different samples of hair/fibers from a variety of animals and people. We had to look at them through microscopes and then draw what we thought each one looked like and identify what it was.
