1. Most Unicellular Eukaryote organisms have the simplest level of organization. (True)
2. There are four major groups of organized tissues that can combine to form organs, and these organs can form systems. The most common tissue of most animals is connective tissue. (b. Connective tissue)
3. Animals of Grade Radiata with radial symmetry have this type of orientation: Oral and Aboral. (b. Oral and Aboral)
4. In protostome body plans, animals develop the mouth first, and in deuterostome animals, they develop the anus first. (a. mouth: anus)
5. With scientific names, the genus name is always capitalized, and the species name is written in small caps. (b. Genus: Species)
6. Scientific names of species can be binomial or trinomial nomenclature. (False)
7. The correct sequence of embryonic development is: Cell Division; Cell Migration; Cell Differentiation. (b. Cell Division; Cell Migration; Cell Differentiation)
8. The correct Domain Classifications are: Eukarya / Bacteria / Archaea. (c. Eukarya / Bacteria / Archaea)
9. The term Archenteron means primitive gut. (True)
10. Three germ layers are formed during the stage of Gastrulation. (True)
11. A Phylogenetic tree is designed to show evolutionary relationships between groups of organisms through ancestral lineage. (True)
12. Sources of phylogenetic information can come from fossil studies, morphological comparisons, cytological and biochemical studies, or research. (True)
13. During embryonic development, animals with true body cavities are formed by one of these two methods, schizocoely-protostome or by enterocoely-deuterostome means. (True)
14. The correct taxonomic sequence of classification for the metazoan (multicellular animal) is: Kingdom – Phylum – Class – Order – Family – Genus - Species. (b. Kingdom – Phylum – Class – Order – Family – Genus - Species)
15. Every animal has an inherited body plan such as symmetry, fluid partitions, the presence of body segments called metameres, and absence or presence of a body cavity. Of these inherited traits, an animal without a body cavity is acoelom. (c. Acoelom)
16. Statement(s): Which is True? All statements are true.
17. According to the interpretation of the Phylogenetic Tree, animals that are in Clades are more closely related. (True)
18. DNA Barcoding: techniques used to determine how old a species may be and its biological fitness. (False)
19. The Theories of Taxonomy: These include the Evolutionary Taxonomy and the Phylogenetic Systematic or cladistics were proposed by these two men: Willi Henning and George Simpson. (b. Willi Henning and George Simpson)
20. In the Phylogenetic tree, Clades are defined as a series of species that share derived characteristics. (True)
21. All Systematic Zoologists would like to reconstruct the evolutionary relationships of all species. (b. to reconstruct the evolutionary relationships of all species)
22. Recognition of species considers: shares common patterns of ancestry, the smallest distinctive group sharing common descent, and has its own niche and geographical range. (d. all answers given (a/b/c) are correct)
23. Species are a reproductive community of populations that occupies a specific niche in nature with the ability to breed outside of its species. (False)
24. In the subdivision of the Animal Kingdom, there are two subdivisions: the Parazoa and the Eumetazoa. (False)
25. The protostome Division includes these animals: Lophotrocozoa and Edysozoa. (b. Lophotrocozoa and Edysozoa)
26. Organismal characteristics are inherited from ancestral to descendant species. (b. Organismal characteristics are inherited from ancestral to descendant species)
27. The Biological Species Concept is associated with T. Dobzhansky and E Mayr in its formation. (b. T. Dobzhansky and E Mayr)
