  • 2. 

    The largest and most inclusive of Linnaeus's taxonomic categories is the

    • Kingdom

    • Order

    • Phylum

    • Species

    Correct Answer
    A. Kingdom
    Explanation
    The largest and most inclusive of Linnaeus's taxonomic categories is the kingdom. This is because the kingdom is the highest level of classification in the Linnaean system and groups organisms based on their overall similarities and characteristics. It serves as a broad classification that helps to categorize and organize a wide range of organisms into distinct groups.

    Rate this question:

  • 3. 

    The three domains are

    • Animalia,Plantae,Archaebacteria.

    • Plantea,Fungi,Eubacteria.

    • Bacteria,Archaea,Eukarya.

    • Protista,Bacterial,Animalia.

    Correct Answer
    A. Bacteria,Archaea,Eukarya.
    Explanation
    The correct answer is Bacteria, Archaea, Eukarya. These three domains represent the three main groups of organisms based on their cellular structure and genetic makeup. Bacteria are prokaryotic organisms that lack a nucleus and membrane-bound organelles. Archaea are also prokaryotes but have distinct genetic and biochemical characteristics that set them apart from bacteria. Eukarya, on the other hand, include all organisms with eukaryotic cells, which have a nucleus and membrane-bound organelles. This classification system helps to categorize and understand the diversity of life on Earth.

    Rate this question:

  • 4. 

    Solely from its name, you know that Rhizopus nigricans must be

    • A plant.

    • An animal.

    • In the genus nigricans.

    • In the genus Rhizopus.

    Correct Answer
    A. In the genus Rhizopus.
    Explanation
    From the name "Rhizopus nigricans," it can be inferred that the organism belongs to the genus Rhizopus. The first part of the name, "Rhizopus," indicates the genus to which the organism belongs. The second part of the name, "nigricans," is likely a specific epithet or species name, indicating a particular species within the genus Rhizopus. Therefore, the correct answer is "in the genus Rhizopus."

    Rate this question:

  • 5. 

    The domain of unicellular prokaryotes that have cell walls containing peptidoglycans is

    • Plantae

    • Fungi

    • Domain

    • Bacterial

    Correct Answer
    A. Bacterial
    Explanation
    The correct answer is bacterial because unicellular prokaryotes with cell walls containing peptidoglycans belong to the domain Bacteria. Bacteria are a large group of microorganisms that are characterized by their single-celled nature and the presence of peptidoglycan in their cell walls. This feature distinguishes them from other domains such as Archaea and Eukarya. Bacteria can be found in various environments and play essential roles in many ecological processes.

    Rate this question:

  • 6. 

    Which of the following is out of order?

    • Kingdom-Phylum-Class

    • Class-Family-Order

    • Family-Order-Genus

    • Genus-Species

    • B and C

    Correct Answer
    A. B and C
    Explanation
    The correct answer is B and C. This is because in the hierarchy of classification, the order should follow the pattern of Kingdom-Phylum-Class-Order-Family-Genus-Species. However, in options B and C, the order is not in accordance with this pattern. In option B, Class is followed by Family, skipping the Order. Similarly, in option C, Family is followed by Genus, skipping the Order. Therefore, both options B and C are out of order.

    Rate this question:

  • 7. 

    A useful classification system does NOT

    • Show relationship.

    • Reveal evolutionary trends.

    • Use different scientific names for the same organism.

    • Chang tha taxon of an organism based on new data.

    Correct Answer
    A. Use different scientific names for the same organism.
    Explanation
    A useful classification system does not use different scientific names for the same organism because it is essential for a classification system to provide consistent and standardized naming conventions for organisms. Using different scientific names for the same organism would lead to confusion and hinder effective communication among scientists.

    Rate this question:

  • 8. 

    A kingdom that includes only heterotrophs is

    • Protista.

    • Fungi.

    • Plantae.

    • Eubacteria.

    Correct Answer
    A. Fungi.
    Explanation
    Fungi is the correct answer because fungi are heterotrophs, meaning they obtain nutrients by consuming organic matter from their environment. They cannot produce their own food through photosynthesis like plants do, and they are not classified as bacteria or protists. Therefore, a kingdom that includes only heterotrophs is Fungi.

    Rate this question:

  • 9. 

    Which of the following shows the evolutionary relationships among a group of organisms?

    • Taxon

    • Molecular clock

    • Binomial nomenclature

    • Cladogram

    Correct Answer
    A. Cladogram
    Explanation
    A cladogram is a diagram that shows the evolutionary relationships among a group of organisms. It is a branching tree-like structure that represents the common ancestry and shared characteristics between different species. Each branch or "clade" represents a common ancestor, and the length of the branches can indicate the amount of time that has passed since the species diverged from their common ancestor. Therefore, a cladogram is the correct answer as it visually represents the evolutionary relationships among organisms.

    Rate this question:

  • 10. 

    A unique trait that is used to construct a cladogram is called a

    • Taxon.

    • Derived character.

    • Domain.

    • Molecular clock.

    Correct Answer
    A. Derived character.
    Explanation
    A unique trait that is used to construct a cladogram is called a derived character. Derived characters are traits that have evolved in a particular lineage and are not found in the common ancestor of that lineage. These traits are used to determine the relationships between different species and to construct a cladogram, which is a diagram that shows the evolutionary relationships among a group of organisms. By analyzing the presence or absence of derived characters in different species, scientists can determine how closely related those species are and how they have evolved over time.

    Rate this question:

  • 11. 

    In classifying organisms, orders are grouped together into

    • Genera.

    • Phyla.

    • Families.

    • Classes.

    Correct Answer
    A. Classes.
    Explanation
    In classifying organisms, orders are grouped together into classes. This is because classes are a higher taxonomic rank than orders and are used to group similar orders together. Classes contain multiple orders that share common characteristics and are further classified under phyla. Families, on the other hand, are lower in rank than orders and represent a narrower classification. Genera are even more specific and are used to group similar species together. Therefore, the correct answer is classes.

    Rate this question:

  • 12. 

    Which animal is grouped within each taxonomic category?

    • Polar bear

    • Starfish

    • Grizzly bear

    • Red fox

    Correct Answer
    A. Grizzly bear
    Explanation
    The Grizzly Bear (Ursus arctos) is grouped within each of these taxonomic categories: Domain (Eukarya), Kingdom (Animalia), Phylum (Chordata), Class (Mammalia), Order (Carnivora), Family (Ursidae), Genus (Ursus), and Species (Ursus arctos). This classification reflects the hierarchical system used in taxonomy to categorize and name organisms based on their evolutionary relationships and shared characteristics.

    Rate this question:

  • 13. 

    Which diagram best illustrates the relationship between a phylum, order, and genus?

    • Genus,order,phylum

    • Genus,phylum,order

    • Phylum.oder,genus

    • Order,genus,phylum

    Correct Answer
    A. Genus,order,phylum
    Explanation
    The correct answer is "genus, order, phylum." In the hierarchy of classification, the genus is a more specific category than the order, which is more specific than the phylum. This means that the genus is a subdivision of the order, and the order is a subdivision of the phylum. Therefore, the diagram that best illustrates this relationship is the one where the genus is at the top, followed by the order, and then the phylum at the bottom.
