a) Cotton: animal origin, Wool: plant origin
b) Cotton: mineral origin, Wool: animal origin
c) Cotton: plant origin, Wool: animal origin
d) Cotton: animal origin, Wool: mineral origin

Answer 1

Cotton has a plant origin as it is made from the cotton plant, while wool has an animal origin as it comes from shearing animals like sheep, llamas, or yaks.

Step-by-step explanation:

Ingrid is analyzing several fibers found at a crime scene and wants to know the origin of cotton and wool. The origin of cotton is from the cotton plant, which provides a cellulose thread that is woven into cotton material, making it a plant origin. Wool, on the other hand, is derived from the shearing of animals such as sheep, llamas, or yak, and retains warmth even when wet, identifying it as of animal origin. Therefore, the correct answer to which origin cotton and wool have is (c) Cotton: plant origin, Wool: animal origin.
