Ovine fleece covering a sheep's body consists of specialized biological fibers known as_________________?
Show answer Hide answer
Answer: C. Wool
Explanation
Ovine fleece covering domestic sheep consists of specialized biological protein fibers known as wool. These natural fibers grow continuously from specialized follicles embedded within the animal skin layers. Wool possesses unique crimp and elasticity traits that differentiate it from standard mammalian hair. Wool fibers are composed primarily of a tough fibrous structural protein called keratin. The outer surface of each wool fiber features microscopic scales that trap insulating air pockets. Shearing sheep annually provides a renewable harvest of natural textile fiber for human use.
The global textile industry relies on wool for manufacturing warm, durable, and moisture-resistant clothing. Farmers carefully manage sheep nutrition and health to maximize the overall quality of fleece. Historical economies in many countries were built largely upon the lucrative international wool trade. Standard hairs on mammals generally lack the specific crimp and felting properties found in true wool. Fleece describes the entire coat collectively rather than the individual specialized biological fibers themselves. Stating none of the above is incorrect because wool accurately names the specialized fibers.
