BSC 1005 UNIT 5 EXAM questions with verified answers
An effect of deforestation has been to Ans✓✓✓ increase the amount
of carbon dioxide in the atmosphere
Analogous structures are evidence of Ans✓✓✓ convergent evolution
Characid fishes are found naturally only in South America and Africa.
Fossils of these fish are not found on any other continents. What is the
most likely explanation of this distribution pattern? Ans✓✓✓ Characid
fishes arose prior to the separation of the African and South American
continents.
Ecology is the study of Ans✓✓✓ interactions between organisms and
their environments
Examine the evolutionary relationships represented in the following
figure. Based upon this diagram, the two most closely related species
are Ans✓✓✓ coyotes and wolves
Examine the two squirrel populations in the following figure. The
populations are separated by a geographic barrier. If after a long period
of time the two species are no longer separated, what evidence is
needed to determine if speciation has occurred? Ans✓✓✓ The two
populations are not interbreeding freely.
, Malaria is an infectious disease transmitted to humans from a parasite
that infects mosquitoes that feed on humans. World health officials
have concerns that climate change may impact the transmission of
malaria into tropical highland areas in Africa. If these concerns turn out
to be valid, they would be evidence for which of the following?
Ans✓✓✓ Global climate change affects the distribution of species.
Molecular systematics might examine all of the following types of data
EXCEPT Ans✓✓✓ anatomical features
Temperate zones Ans✓✓✓ have milder climates than the tropics
The figure below shows the percent of selected DNA sequences that
match between a chimpanzee and other primates. These data support
the hypothesis that Ans✓✓✓ the chimpanzee's closest surviving
relative is humans
The first basic idea of evolutionary adaptation can be traced back to
Ans✓✓✓ Lamarck
The fossil record suggests that whales Ans✓✓✓ are closely related to
land mammals such as pigs, hippos, and cows
The original source of genetic variation that serves as the raw material
for natural selection is Ans✓✓✓ mutation
