Polyphyletic groups are problematic in taxonomy because they:
Include all descendants of a common ancestor.
Include the most recent common ancestor and all its descendants.
Do not include the most recent common ancestor of all members.
Represent a single evolutionary lineage.
Which of the following is not a valid reason why the morphological species concept can be problematic?
It can be difficult to distinguish between intraspecific variation and interspecific differences.
Cryptic species may be morphologically identical but reproductively isolated.
It requires detailed genetic analysis.
Morphological traits can be influenced by environmental factors leading to phenotypic plasticity.
A newly discovered organism exhibits radial symmetry in its larval stage but bilateral symmetry as an adult. Its body cavity is formed by splitting of the mesoderm. It possesses a water vascular system. To which phylum does this organism MOST likely belong?
Echinodermata
Chordata
Cnidaria
Annelida
Which of the following features is NOT characteristic of the members of the kingdom Fungi?
Heterotrophic mode of nutrition
Presence of chlorophyll a and b
Cell wall made of chitin
Reproduction by spores
A scientist discovers a new species with the following characteristics: eukaryotic, multicellular, photosynthetic, lacks vascular tissue, exhibits alternation of generations with a dominant gametophyte. This organism MOST likely belongs to which plant group?
Pteridophyta
Bryophyta
Gymnosperms
Angiosperms
Which of the following combinations of characters is unique to the phylum Chordata?
Bilateral symmetry, triploblastic, coelomate
Notochord, dorsal hollow nerve cord, pharyngeal gill slits, post-anal tail
Closed circulatory system, segmented body, jointed appendages
Radial symmetry, diploblastic, acoelomate
The 'Five Kingdom Classification' system proposed by R.H. Whittaker does NOT primarily consider which of the following criteria?
Cell structure (prokaryotic vs. eukaryotic)
Mode of nutrition (autotrophic vs. heterotrophic)
Thallus organization (unicellular vs. multicellular)
Detailed evolutionary relationships based on genetic analysis
Certain members of the kingdom Protista exhibit characteristics of both plants and animals. Which of the following combinations correctly identifies a protist with plant-like and animal-like features, respectively?
Diatoms (plant-like: cell wall of silica); Paramecium (animal-like: cilia for movement)
Euglena (plant-like: photosynthetic); Amoeba (animal-like: heterotrophic by phagocytosis)
Slime molds (plant-like: saprophytic); Dinoflagellates (animal-like: bioluminescence)
Amoeba (plant-like: pseudopodia); Paramecium (animal-like: heterotrophic)
A museum researcher discovers an unknown arthropod specimen. Which taxonomical aid would be LEAST helpful in its initial broad classification?
Manual
Monograph
Flora
Key
While creating a phylogenetic tree for a genus of insects, a taxonomist finds conflicting information between a recently published monograph and a classical museum catalogue. Which resource should be prioritized and why?
The museum catalogue, due to its historical precedence and established nomenclature.
The monograph, as it likely incorporates newer molecular data and revised classifications.
Equal weight to both, synthesizing the information.
Neither, consult a field guide for practical identification.
