1) Dogs (Canis familiaris) are most
closely related genetically to which of
the following organisms? Why?
African hunting dog (Lycaon pictus)
Gray wolf (Canis lupus)
Grizzly bear (Ursus arctos)
Domestic cat (Felis catus)
4) The diagram illustrates how some
characteristics of the horse have
changed over time. Along with the
difference in size, what is another
anatomical difference between the
modern horse and its ancestors?
2) During a severe drought a dry
lake was explored for fossils. The
diagram represents the fossils
uncovered and the layers they were
in. According to this information, this
area was once a —
5) The table shows a comparison of
some amino acids found in
cytochrome c. The two organisms in
the table that are most closely
related are —
3) This area was once what type of
environment?
11) Which classification is most
specific?
12)What characteristics of members
of the plant kingdom distinguishes
them from members of the animal
kingdom?
6) In the case above, why is it
important that we classify things
scientifically?
7) Knowledge of which of these is
most important in classifying this
new organism into a kingdom?
8) The bullfrog, Rana catesbeiana, is
most closely related which of the
following organisms? Why?
Spotted chorus frog, Pseudacris clarki
Asian flying frog, Polypedates leucomystax
Northern leopard frog, Rana pipiens
African bullfrog, Pyxicephalus adspersus
9) A laboratory investigation included
examining prepared slides of pond
water. Single-celled organisms with
a nucleus and either cilia or flagella
were visible. These organisms
probably belong to the kingdom —
10) Multicellular eukaryotes that are
usually mobile and obtain food from
other organisms probably belong to
the kingdom-
13) This organism most likely is a
member of which kingdom?
14) A team of scientists is studying
the fossils in the cross-section of
rock shown below.
17) According to the table above
which organisms are the most
closely related?
18) In what way are bacteria
extremely important to agriculture?
In which layers of rock are the oldest
leaf and fish fossils found?
15) According to the theory of natural
selection, a species that lacks the
variations necessary to adapt to a
changing environment will most likely
–
19) A cell is observed through a
microscope. The cell is found to
have a cell wall, a cell membrane,
and numerous ribosomes. The cell
does not have a nucleus. This cell is
most likely what type of cell and what
Kingdoms are they found in?
20) What is a nonliving structure that
contains genetic material and cannot
metabolize nutrients? Draw a simple
diagram of its structure.
21) What does a virus need in order
to multiply?
16) The diagram above shows
undisturbed sedimentary rock strata
containing fossils. Summarize the
history of this area?
22) Explain why antibiotics can treat
flu-like symptoms caused by bacteria
but are ineffective against flu?
23) What is found in both cells and
viruses?
24) People infected with the human
immunodeficiency virus (HIV) have
an increased risk of dying from
secondary infections. Explain how
HIV increases the danger of
secondary infections?
28) How would you treat a person
with a respiratory infection if they
have an elevated level of protein in
the blood?
25) Viruses can be transmitted in a
variety of ways. The virus that
causes SARS (severe acute
respiratory syndrome) can be
transmitted when an infected person
coughs or sneezes. This virus is
transmitted in a manner most similar
to the transmission of —
29) Some bacteria thrive in hostile
environments, such as salt flats,
boiling-hot springs, and carbonaterock interiors, what kingdom would
they be found in?
26) Viruses differ from bacteria in
that all viruses must reproduce in
what—
30) The diagram above represents a
virus with its surface markers. The
diagrams below show various animal
cells with receptor sites. Which of the
following cells is most likely affected
by this virus?
27) Explain what is happening to the
small population of M. tuberculosis
that is surviving?
31) Which statement above makes
the most valid argument in favor of
receiving the flu vaccine?
32) What structure does the protist in
the above diagram use to move?
