Which of the following is not a special part of animals?
a. beak
b. head
c. gills
d. wings
The correct answer and explanation is:
The correct answer is b. head.
Explanation:
The head is a common body part found in nearly all animals, not a special part. The head serves as the primary site for the brain, sensory organs (like eyes, ears, and nose), and mouth. It is a fundamental and universally present structure in the body plans of animals, rather than a specialized feature like the other options.
- Beak: This is a special structure found primarily in birds, some reptiles, and certain species of mammals like the platypus. A beak is an adaptation to an animal’s diet, providing a specialized mechanism for feeding. It allows birds to manipulate food, break shells, or catch prey.
- Gills: Found mainly in fish and some amphibians, gills are specialized organs for breathing in water. They extract oxygen from water and expel carbon dioxide, enabling these animals to survive in aquatic environments.
- Wings: Wings are specialized appendages seen in birds, bats, and insects. These structures allow animals to fly, providing them with the ability to cover large distances quickly and efficiently, find food, escape predators, or migrate.
While the head is universally present across animals, features like beaks, gills, and wings are more specialized adaptations tailored to specific needs of an animal’s environment, diet, or behavior. Therefore, the head is not considered a specialized feature in the same sense as these other body parts.
