Question 14

Snake is a terrestrial vertebrate that has scales.

A snake is a type of terrestrial vertebrate known for its scaly skin, which serves various functions including protection and moisture retention.

A) Snake

This option is correct because snakes are indeed terrestrial vertebrates that possess scales covering their bodies. These scales are made of keratin and play a crucial role in their adaptation to land environments.

B) Elephant

Elephants are terrestrial vertebrates, but they do not have scales; instead, they have thick, wrinkled skin. Their skin is adapted for different environmental conditions but does not feature scales like those of reptiles.

C) Salmon

While salmon are vertebrates and have scales, they are not terrestrial; they are primarily aquatic creatures found in freshwater and marine environments. Therefore, this option does not meet the requirement of being terrestrial.

D) Ant

Ants are not vertebrates; they are invertebrates belonging to the insect class. This option is incorrect as it does not fit the criteria of being a terrestrial vertebrate with scales.

Conclusion

The snake is the only option that correctly identifies a terrestrial vertebrate with scales. Other choices either do not qualify as vertebrates or lack the characteristic of scales, thus confirming that the snake is the definitive answer.
