The lizard is well-adapted to live in human dwellings. Which function of its adaptations is incorrectly described?
| Adaptation | Function | |
| A | Long, sticky tongue | To catch fastmoving prey |
| B | Long, narrow and flat body | To crawl between narrow crevices and spaces easily |
| C | Sticky pads on the underside of the feet | To walk on walls and ceilings without falling |
| D | Tail that can drop off and wriggles for a while. | To attract mates for reproduction |
Lizards, if get captured by the tail, shed (drop off) the tail and are able to flee. The detached tail continues to wriggle for some time creating a deceptive sense of continued struggle and distracting the predator’s attention from the fleeing prey animal. The lizard can partially regenerate its tail over a period of weeks. Thus, it is a self-defense mechanism to elude a predator’s grasp and not to attract mates for reproduction.
