
Items may address the conditions required for the origin of life on
Earth but may not require specific knowledge of the age of Earth or
its eras, periods, or epochs.
 Items may assess how contributions of scientists such as Pasteur,
Oparin, Miller and Urey, Margulies, or Fox aided in the development
of the scientific explanation of the origin of life but will not assess
what each scientist contributed.
 Items assessing the origin of organic molecules, chemical evolution,
and/or eukaryotic cells should be conceptual.
 Items may refer to the endosymbiotic theory but may not assess the
term in isolation.
 Items assessing a scientific claim are limited to the scientific

What You Need To Know
You need to know the conditions required for natural selection to occur.
These include:competition, limited
resources, overproduction of offspring, inherited variation, and the struggle
to survive, which result in
differential reproductive success
You need to understand genetic drift and gene flow
. You need to know how mutation and genetic recombination increase genetic
variation.
33.
Certain traits become more or less common in a population as a result of
differential reproductive
success. Which of the following examples describes the condition most likely
to change the
frequency of a trait within a population?
.A large coal mine has been closed and abandoned, thus providing a brown bat
population with a new hibernation site.
B. The food availability for a population of brown bats is severely
diminished when a drought reduces
the number of mosquitoes
C. Injured brown bats are taken to a rehabilitation center where the animals
can recover before they are released into
the wild.
D.After a gestation period of 50 days, female brown bats give birth to
healthy pups that remain with their mothers for

temperatures found in the lava of volcanoes. Which
statement best explains how bacteria could survive in this environment?
A.Bacteria are small enough not to be killed by heat.
B.Bacteria are simple organisms and can live in any Conditions.
C.Bacteria have mutated and those suited to the environment survive there.
D.Bacteria grow faster in hot conditions and so are suited to the
environment.
35.During his trip to the Galapagos Islands, Charles Darwin observed that
finches on different islands had different
features.
Ultimately, how did this observation contribute to Darwin’s theory of natural
selection?
A.He concluded that every instance of species variation results in a
beneficial mutation.
B He concluded that mutation inhibits the chance that an organism will adapt
to its environment.
