Animals have the innate ability to escape from predation. Examples for the same are given below. Select the incorrect example.
Correct answer: C. Poison fangs in snakes
- A. Colour change in Chamaeleon.
- B. Enlargement of body size by swallowing air in puffer fish.
- C. Poison fangs in snakes
- D. Melanism in moths.
Explanation
Colour change in Chameleon and melanism in moths are examples of camouflage in animals adapted to prevent predation from prey. As a defence mechanism puffers have the ability to inflate rapidly, filling their extremely elastic stomach with water (or air) until they are almost spherical. This prevents them from being identified by the predator. But poison fangs in snakes are a method adopted for preying and not escaping predation.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
