Relationship between Skin Features and Classes of Vertebrates

The relationship between skin features and classes of vertebrates can be observed by examining the specific characteristics of the skin in different groups of animals. In this case, we are given a set of skin features and asked to identify the corresponding letters for the classes of vertebrates to which these features are characteristic. Let's analyze each feature and its corresponding class:

- A - Protects from desiccation: This feature refers to the ability of the skin to prevent water loss. Among the given options, the class of vertebrates that is known for having skin that protects from desiccation is Amphibians. Amphibians have moist skin that helps them to stay hydrated and prevents excessive water loss.

- E - Facilitates water absorption: This feature refers to the ability of the skin to absorb water. Among the given options, the class of vertebrates that is known for having skin that facilitates water absorption is Amphibians. Amphibians have permeable skin that allows them to absorb water directly through their skin.

- R - Has keratinized scales: This feature refers to the presence of scales made of keratin on the skin. Among the given options, the class of vertebrates that is known for having keratinized scales is Reptiles. Reptiles have scales made of keratin that provide protection and help reduce water loss.

- Z - Contains abundant glands: This feature refers to the presence of numerous glands in the skin. Among the given options, the class of vertebrates that is known for having abundant glands in the skin is Amphibians. Amphibians have various types of glands in their skin, including mucous glands and poison glands.

- L - Participates in gas exchange: This feature refers to the ability of the skin to exchange gases, such as oxygen and carbon dioxide. Among the given options, the class of vertebrates that is known for having skin that participates in gas exchange is Amphibians. Amphibians have thin and permeable skin that allows for gas exchange.

- S - Does not contain glands: This feature refers to the absence of glands in the skin. Among the given options, the class of vertebrates that is known for having skin that does not contain glands is Reptiles. Reptiles have dry skin that lacks glands.

Based on the analysis above, the corresponding letters for the classes of vertebrates are:

Amphibians: A, E, Z, L Reptiles: R, S

Therefore, the answer to the given question is: AELRZS.
