Which of the following statements is not true?

Options

A. The body colour offers it protective colouration
B. Summer sleep of frog is called aestivation
C. Tail is present in the lifecycle of frog
D. Mouth of cockroach is bounded by a pair of lips

Explanation

To determine which statement is not true, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Statement 1: "The body color offers it protective coloration."**
- This statement is true. Frogs can change their body color to blend in with their environment, a process known as camouflage. This adaptation helps them avoid predators, thus providing protective coloration.

2. **Statement 2: "Summer sleep of frog is called as activation."**
- This statement is false. The summer sleep of frogs is known as estivation, not activation. Frogs are cold-blooded and enter a state of inactivity during extreme temperatures, which varies between hibernation in winter and estivation in summer.

3. **Statement 3: "Tail is present in the life cycle of frog."**
- This statement is true. Frogs undergo indirect development, where the larval stage (tadpole) has a tail. The tadpole eventually metamorphoses into an adult frog, which does not have a tail.

4. **Statement 4: "Mouth of cockroach is bounded by a pair of lips."**
- This statement is false. The mouthparts of a cockroach are not bounded by a pair of lips. Instead, they consist of various structures including the labrum (upper lip), mandibles, maxillae, and labium (lower lip). Therefore, the statement is misleading as it implies the presence of a simple pair of lips.

### Conclusion:
The statement that is not true is **Statement 2: "Summer sleep of frog is called as activation."**
