Example Question #11 : Use The Taxonomic Classification System
What is true about the theory of gradualism?
It stands in opposition to the theory of punctuated equilibrium
All of these
Change is uniform
Change is slow and gradual
All of these
Gradualism is a theory of evolutionary biology that stands in contrast to the theory of punctuated equilibrium. In this theory, change (or evolution) is slow, gradual, and uniform. Adaptation occurs over a long period of time and is observed in small changes.
Example Question #12 : Use The Taxonomic Classification System
Which of the following best describes the difficulties associated with the study of phylogenetics?
Horizontal gene transfer and hybridization
Hybridization
Horizontal gene transfer
Neither horizontal gene transfer nor hybridization
Horizontal gene transfer and hybridization
Phylogenetics has several difficulties that complicate the development of accurate phylogenetic trees. Relationships between organisms on a genetic level are incredibly complicated, making it difficult for scientist to create clean and precise phylogenetic trees. These difficulties include hybridization, horizontal gene transfer, and convergent evolution.
Example Question #13 : Use The Taxonomic Classification System
Fungi belong to the __________ of __________.
domain . . . eukarya
kingdom . . . eukarya
kingdom . . . bacteria
domain . . . bacteria
class . . . archaea
domain . . . eukarya
There are 3 domains in which all organisms are classified - Eukarya, Bacteria, and Archaea. Fungi is the name of one the kingdom classifications. The order for the classification is as follows: domain, kingdom, phylum, class, order, family, genus, species. Therefore, Fungi falls under the Domain of Eukarya.
Example Question #14 : Use The Taxonomic Classification System
Which is not one of the three domains?
prokarya
archaea
eukarya
bacteria
prokarya
Domain is the broadest taxonomic category, and includes bacteria, archaea, and eukarya; all living organisms can be classified into one of these three domains.
Example Question #15 : Use The Taxonomic Classification System
From most broad to specific, how are organisms classified?
Domain-> Kingdom-> Phylum-> Class-> Order-> Family-> Genus-> Species
Order> Kingdom-> Phylum-> Domain> Class> Genus> Family> Species
Kingdom> Domain> Class> Phylum> Order-> Family-> Genus-> Species
Domain-> Phylum> Kingdom> Class-> Order-> Family-> Genus-> Species
Domain-> Kingdom-> Phylum-> Class-> Order-> Family-> Genus-> Species
There are eight taxonomic categories, with domain most inclusive and each subsequent category becoming more specific.
Example Question #16 : Use The Taxonomic Classification System
Which is a species?
Eukarya
Arthropoda
Felis catus
Protista
Felis catus
Arthropoda is a phylum, eukarya is a domain, and protista is a kingdom. There are eight taxonomic categories (Domain-> Kingdom-> Phylum-> Class-> Order-> Family-> Genus-> Species) with domain being most inclusive and each subsequent category becoming more specific.
Example Question #17 : Use The Taxonomic Classification System
Which is not one of the kingdoms?
fungi
protista
plantae
bacteria
bacteria
There are eight taxonomic categories (Domain-> Kingdom-> Phylum-> Class-> Order-> Family-> Genus-> Species) with domain being most inclusive and each subsequent category becoming more specific. Bacteria are not a kingdom; bacteria are one of the three domains. Kingdom includes fungi, prokaryotes, protista, plantae, and animalia.
Example Question #18 : Use The Taxonomic Classification System
Which is a characteristic unique to the domain eukarya?
Membrane bound organelles
No histones
Cell walls contain peptidoglycan
No organelles
Membrane bound organelles
The three domains include bacteria, eukarya, and archaea. Eukarya contain membrane bound organelles, have histones (which are proteins in chromatin), and cell walls do not contain peptidoglycan.
Example Question #19 : Use The Taxonomic Classification System
Which is a characteristic of the kingdom animalia?
Prokaryotic cells
Unicellular
Autotrophic
Heterotrophic
Heterotrophic
Organisms within the kingdom animalia have eukaryotic cells, are multicellular, and are heterotrophic (receives its nutrition through consuming other organisms).
