key and a microscope to classify the animal. How should this animal be classified?
A.
B.
C.
D.
Arthropoda
Annelida
Mollusca
Platyhelminthes

water. The feature that distinguishes euglena from cyanobacteria is the —
A. ability to maintain homeostasis
B. presence of ribosomes
C. ability to reproduce
D. presence of a nucleus
4. True or false
Domain is the most specific taxonomic group available. T or F

examples of the many types of arthropods. Which of these arthropods are most closely
related?
A. Arthropods of the same family
B. Arthropods of the same class
C. Arthropods of the same genus
D. Arthropods of the same species
6. The limbs of several organisms are shown in the illustrations below. Scientists sometimes
compare the limbs of these organisms to look for evidence of common ancestry.
These limbs provide evidence of common ancestry because they —
A.
B.
C.
D.
have the same basic structure
perform the same function
are the same size
are parts of mammals
7. Which of the following is true about Archeabacteria?
Archaebacteria
A. Contain a nucleus but can survive for a long period of time.
B. Are prokaryotes and the oldest form of life on earth because they can withstand harsh
conditions
C. Are always extremely small and reproduce sexually
D. Are always harmful in our environment
8. What is taxonomy?
A. The scientific study of how living things are classified
B. The name of Aristotle’s classification system
C. The process of observing a living organisms behavior
D. The process used by geologist to classify rocks
9. Loriciferans are microscopic multicellular animals that live in various marine sediments.
Scientists have discovered genera of Loriciferans in a deep-sea habitat that lacks oxygen.
Before this discovery, some prokaryotes and some unicellular eukaryotes were known to
inhabit anaerobic environments. Among the newly discovered Loriciferans is Spinoloricus sp.
nov., which is pictured below.
Scientists determined that organisms of the genus Spinoloricus were eukaryotes and not
prokaryotes because Spinoloricus cells have —
A.
B.
C.
D.
flagella
hereditary material
cell walls
nuclear membrane
10.Methanogens, thermophiles, and halophiles are some of the most primitive life-forms found
on Earth and thrive in very harsh environments. These unicellular, prokaryotic organisms most
likely belong to which of the following kingdoms?
A. Fungi
B. Eubacteria
C. Protista
D. Archaebacteria
11.Prokaryotic organisms make up the
A. Archaebacteria, Eubacteria, and Protista kingdom
B. Archaebacteria and Protista kingdom
C. Protista and Eubacteria kingdom
D. Eubacteria and Archaebacteria kingdom
12.The diagram shows taxonomic groups and a major distinguishing characteristic of all but two
of them.
Which characteristics will be used to complete the chart?
13. All living organisms have a 2 part identification or scientific name describing their structure so
that scientist all over the world know they are talking about the same animal. Which are the
two correct classifiers below?
A. Genus, species
B. Kingdom, class
C. Family, species
D. Phylum, order
14.The diagram above shows a model of species divergence among some primates. If this model
is correct, the greatest genetic differences would be found in the DNA sequences of which
two species?
A. Tarsius bancanus and Cebus albifrons
B. Macaca sylvanus and Macaca mulatta
C. Hylobates lar and Pongo pygmaeus
D. Pan troglodytes and Lemur catta
15.Frogs and toads belong to the order Anura. The smallest organism in this order is about 7
millimeters long, while the largest member is about 30 centimeters long. Which of these lists
best describes this order?
16.An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such
as the one shown below, is based on molecular data. It can be used to represent evolutionary
relationships within a group of organisms that are hypothesized to have descended from a
common ancestor.
Which statement is best supported by the information in this dendrogram?
A.
B.
C.
D.
Lesser pandas are more genetically similar to giant pandas than they are to raccoons.
Brown bears are more genetically similar to giant pandas than they are to sun bears.
Lesser pandas are more genetically similar to raccoons than they are to giant pandas.
The bear species are all more genetically similar to dogs than they are to giant pandas.
17.A student wants to use the Venn diagram below to show the characteristics of two kingdoms
of organisms. The characteristics that the two kingdoms share will be listed in the shaded area
where the circles intersect.
Which of these is a characteristic that the student should list in the shaded part of the diagram?
(This is question 17)
A.
B.
C.
D.
Heterotrophic
Mobile
Prokaryotic
Multicellular
18.Adult mountain lions (Puma concolor) are almost 2 meters long. They have a black spot over
each eye. The common names used throughout the United States for this species are listed
below
Why is it best for scientists to use the name from the standardized taxonomic system?
A.
B.
C.
D.
The standardized name differentiates mountain lions and pumas.
The standardized name is less descriptive of the animal that has been observed.
Communication with other scientists about mountain lions will be reduced.
All scientists will be using one name for mountain lions.
19.
Using the dichotomous key, classify an organism that has small or no wings, shorter rear legs,
not a horned head and small eyes.
A. mosquito
B. butterfly
C. termite soldier
D. grasshopper
