Question

Read the following paragraph and choose the correct answer from the given options.

Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. All animals included in class Mammalia are warm-blooded, hairy, and have mammary or milk-producing glands. While animals of class Reptilia are cold-blooded and their bodies are covered with dry epidermal scales.

• A. Class is a taxon while Mammalia is a category.
• B. The taxa Mammalia and Reptilia both have the same category because they are both classes.
• C. Class is a category while Mammalia is a taxon.
• D. Class is a rank while Vertebrata is a category.

Answer 1

The correct option is B The taxa Mammalia and Reptilia both have the same category because they are both classes.

• Taxon and category differ from each other.
• The taxon is the group of organisms under the same category, while the category represents the level of that taxon. For example, both Mammalia and Reptilia are taxa and both have the same category because they are both classes in the taxonomic hierarchy.
• Vertebrata is a subphylum that has a higher rank in the taxonomic hierarchy than class Mammalia and Reptilia.

So, the correct answer is option B.
