Chapter 17 Bio
MC: Quercus Rubra : Quercus phellos ::
Aphis pomi : Aphis gossypii
MC: Which of the following was not a consideration for Carolus Linnaeus when he developed his system of nomenclature of organisms?
It should include detailed descriptions of an organism in its name.
MC: Which of the following scientists developed the system of classifying organisms by assigning them a genus and species name?
Linnaeus
_________ devised the two-name system of naming organisms.
Linnaeus
MC: The organism Quercus Phellos is a member of the genus
Quercus
MC: The red maple is also known as Acer rubrum. Its scientific name is
acer rubrum
MC: Scientists don't use the common names of organisms because
an organism may have more than one common name, an organism rarely has the same name in different languages, common names are too ambiguous. All of the Above
Corals, spiders,and rodents all belong to the kingdom ____________
animalia
Biologists of Linnaeus's time classified every living thing as either plants or ___________
animals
MC: Simple, non-nucleated organisms that use hydrogen to produce methane are in the domain
archaea
MC: Two organisms in the same class but different orders
are in the same phylum
MC: The DNA sequences of two species of sharks would
be more similar than the DNA sequences of a shark and a dolphin
MC: As we move through the biological hierarchy from the kingdom to species level, organisms
become more similar in appearance
Each kind of organism on Earth is assigned a unique two-word ____________________
binomial nomenclature
The variety of organisms are all taxonomic levels is called ___________
biodiversity
MC: Refer to the illustration above. A branching diagram like the one shown is called a
cladogram
MC: Kingdoms are divided into phyla, and each phylum is divided into
classes
Cladistics uses shared and ________ characters to group taxa.
derived
MC: Refer to the illustration above. Each particular feature, such as dry skin, that is used to assign an organism to a group is called a(n)
derived character
A kingdom is divided into phyla when animals being classified or into __________ when plants are being classified.
division
The domain of the three-domain system of classification are Archaea, Bacteria, and ___________
eukarya
MC: An organism that breaks down organic matter, which it then absorbs, is in the kingdom
fungi
MC: Multicellular, nucleated heterotrophs that always obtain food by absorbing nutrients from the environment belong to the kingdom
fungi
Refer to the illustration above. Organisms 4 belongs to the kingdom ________
fungi
The first word of a scientific name indicates the ______ to which the organism belongs.
genus
MC: Taxonomy is defined as the science of
grouping organisms according to their characteristics and evolutionary history
MC: Today, biologists classify organisms by their
physical similarities, chemical similarities, behavioral similarities, All of the Above
MC: Most multicellular, nucleated autotrophs that carry on photosynthesis belong to the kingdom
plantae
MC: Phylogenetic trees depict
presumed evolutionary relationships based on variety of types of evidence
Eukaryotic organisms the lack specialized tissue systems are member of the kingdom _______
protista
MC: Nearly all single-celled eukaryotes that are either heterotrophic or photosynthetic belong to the kingdom
protista
MC: The kingdom defined as including any eukaryotes that are not plants, animals, or fungi is the kingdom
protista
MC: Carl Woese proposed the three-domain system of classification based on the examination of
ribosomal RNA
MC: The three domain system of classification is based on similarities and differences in ___, which the six kingdom system is based on similarities and differences in ___.
ribosomal RNA; embryological development, fossils, physical feature, and various molecular structures.
A genus is subdivided into smaller groups called _________
species
MC: The lowest hierarchy level in biological classification in the
species
MC: Which of the following is the least inclusive classification group?
species
Aristotle classified plants on the basis of difference in their __________
stems
The science of naming and classifying organisms is called _______________
taxonomy
MC: Poison ivy is also known as Rhus toxicodendron. It species identifier is
toxicodendron
MC: The scientific name of an organism
is the same for all scientist all over the world
MC: A mushroom is difficult to classify in Linnaeus's two-kingdom classification system because
it doesn't seem to fit into either kingdom
MC: The correct order of the biological hierarchy from the kingdom to species is
kingdom, phylum, class, order, family, genus, species
All scientific names are made up of two words that are often derived from the __________ language
latin
MC: Organisms in different genera
mat share the second world of their scientific names, may be in the same family, may be in different orders. All of the Above
MC: Two organisms in the same order but different families may
may be similar than two organisms in different classes, have the same species identifier, be in the same class. All of the Above
MC: An organisms can have
one genus name and one species identifier
MC: Which of the following is (are) used in systematic taxonomy to classify organisms?
patterns of embryological development, homologous features, amino acid sequences of proteins, All of the Above
The evolutionary history of a species is called its _________
phylogenetics
MC: Class : family ::
phylum : order
