,A botanist studied two groups of rice
plants to determine how they are related.
Both groups of plants have similar
shapes, but one group has longer stalks.
When the botanist cross-pollinated plants
from one group with plants from the
other group, the seeds produced did not
sprout or grow.
Which of the following conclusions is
best supported by this information?
A. The two groups are the same species
because the plants have similar
shapes.
B. The two groups are different species
because they have differently sized
stalks.
C. The two groups are different species
because the seeds produced cannot
sprout or grow.
D. The two groups are the same species
because the plants were cross-
pollinated and produced seeds.
C. The two groups are different species
because the seeds produced cannot
sprout or grow.
The diagram below represents a
biological process involving DNA.
What process is represented?
A. fertilization
B. mutation
C. replication
D. translation
C. replication

generation time.
B. It has hundreds of chromosomes and
a long lifespan.
C. It has a simple cell structure and
reproduces rapidly.
,D. It has many kinds of organelles and
reproduces sexually.
C. It has a simple cell structure and

Protein pumps actively transport ions
across a cell's plasma membrane. What
molecule directly supplies the energy
required for this transport?

B. cholesterol
C. oxygen
D. tRNA
A. ATP
Scientists hypothesized that several
species of frogs called tiger frogs
evolved from a recent common ancestor.
The hypothesis was based on fossil
evidence and on physical similarities
among living species.
Which of the following provides the
best additional support for the scientists'
hypothesis?
A. Tiger frogs have longer life spans
than other frog species.
B. Tiger frogs have the same diet and
all use enzymes to digest food.
C. Tiger frogs live near each other and
are all preyed upon by the same
predator species.
D. Tiger frogs have similarities in their
mitochondrial DNA that are not
shared by other frog species.
D. Tiger frogs have similarities in their
mitochondrial DNA that are not
shared by other frog species.

of chromosomes that it has.
D. Plasmodium can create zygotes that
the immune system does not attack.

To treat malaria, doctors must know
which species of Plasmodium is causing
the disease. Which of the following
statements best explains why doctors
must identify the Plasmodium species
involved before treating the disease?

its highest rate of infection at a
different time of the year.

evolved different levels of resistance
to different medications.
C. Some Plasmodium species produce
large numbers of gametes, and some
Plasmodium species produce small
numbers of gametes.
D. Some Plasmodium species have
a prokaryotic cell structure, and
some Plasmodium species have a
eukaryotic cell structure.
