Cuticle in Ascaris is an adaptation for
A. Parasitism
B. Growth
C. Reproduction
D. Locomotion
A. Parasitism
The cuticle in Ascaris is an adaptation for A. Parasitism.
To determine the correct answer, we need to understand what the cuticle is and how it is related to Ascaris. The cuticle of Ascaris is a tough outer layer that covers the body of the organism. It is a protective covering that helps Ascaris in various ways.
For option A: Parasitism, the cuticle helps Ascaris survive in the host's body. Ascaris is a parasitic roundworm that lives in the intestines of its host, where it benefits from taking nutrients from the host. The cuticle helps protect Ascaris from the host's digestive system, immune responses, and other external factors.
For option B: Growth, although the cuticle may contribute to the overall growth of Ascaris by providing protection, it is not its primary function.
For option C: Reproduction, the cuticle does not directly play a role in the reproductive process of Ascaris.
For option D: Locomotion, while the cuticle does assist in the movement of Ascaris by reducing friction and allowing for smooth motion, it is not its main adaptation for locomotion.
Considering the above explanations, the correct answer for the adaptation of the cuticle in Ascaris is:
A. Parasitism
