Which statement best explains why two of the sea lions are more closely related?
A. California Sea Lion and Galapagos Sea Lion because they belong to the same Kingdom
and Phylum.
B. New Zealand Sea Lion and California Sea Lion because they belong to the same Genus
and Species.
C. Galapagos Sea Lion and New Zealand Sea Lion because they belong to the same Class
and Order.
D. California Sea Lion and Galapagos Sea Lion because they belong to the same Family and
Genus.

4. A tree frog population lives in the canopy of a tropical rain forest. In this tree frog
population, a mutation occurs that results in a new allele for skin coloration causing stripes
on their legs. Which of the following factors has the greatest effect on whether leg stripes
will become more common in the tree frog population?
A.
B.
C.
D.
If the reproduction rate of the tree frog population remains constant over time.
If the new allele for stripes is presented more in females in the tree frog population.
If the new allele for stripes increases the survival of the tree frogs in their environment.
If enough food and water are available in the rain forest canopy for the tree frog
population.

5. Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly
across deep snow because they have large feet that don’t sink into the snow. Rabbits without
this adaptation move more slowly across the snow. Which statement best justifies how the
rabbit population changes over time.
A. The rabbit population with smaller feet will increase because they have a positive
adaptation.
B. The rabbit population with larger feet will decrease because they have a negative
adaptation.
C. The rabbit population with larger feet will increase because natural selection has favored
this genetic change.
D. The rabbit population with smaller feet will become extinct because natural selection has
favored this genetic change.

6. On a small isolated island, there is a single species of seed-eating birds. Individual birds are
able to eat seeds that are within 2 mm (larger or smaller) than their beak depth. The
distribution of individuals is shown in the figure below.
A long drought caused the plant species that produced seeds between 3 - 9 mm in size to go
extinct. What does the Theory of Natural Selection predict will most likely happen to the
population of seed-eating birds over time?
A. It will permanently shrink to approximately 25% of its current size.
B. It will go extinct because there aren’t enough seeds to support all of the individuals.
C. It will diverge into two species: one that eats small seeds and one that eats large seeds.

D. It will adapt and the birds that ate the medium sized seeds will learn to eat fish, insects, or
other animals.
SC.7.L.15.2
7. A termite population was sprayed with a certain brand of insecticide, a poison that kills
termites. After being sprayed, the number of surviving termites within the population were
counted and recorded as percentage of the total. This process was repeated until a total of six
generations of termites had been sprayed. The results are shown in the table below.
Termite
Generation
Percentage of
Surviving
Termites after
Spraying
1
5%
2
10%
3
25%
4
40%
5
60%
6
80%
Which conclusion best explains the data represented above?
A. Generation 1 did not survive because it had several members that were old and weak.
B. Generation 5 had fewer numbers of termites surviving than Generation 2 due to a smaller
initial population.
C. The population of termites decreased from generation 1 to 6 because the insecticide killed
more of the offspring.
D. The survival rate of the termite population increased from generation 1 to 6 which may
be due to insecticide resistance in the termite population.
SC.7.L.15.3
8. Rainfall in a tropical region has been below average for 10 consecutive years. Insect species
adapted to dry conditions are much more plentiful at the end of the 10 years. Which of the
following statements best explains the increase in the population of these insects?
A.
B.
C.
D.
Biodiversity in the region has increased due to the dry conditions.
Insects with a high tolerance for dry conditions have moved out of the region.
Natural selection has favored insect species with high tolerance for dry conditions.
Natural selection has selected against insect species that are adapted for dry conditions.

9. Global warming occurs because of increased greenhouse gases such as carbon dioxide in our
atmosphere. Carbon dioxide forms carbonic acid when dissolved in water. The increase of
carbonic acid in the ocean waters causes a decrease in ions necessary for many sea creatures
such as plankton and coral to make bones and shells. Based on the information above which
of the following statements best explains what would occur.
A. Plankton and sea coral would make immediate adaptations through genetic mutations to
adjust to the changes in the environment.
B. The ocean water would change its current so that the acidic water is relocated to another
area and allow plankton and sea coral to survive.
C. The ocean water would change its composition to reduce the amount of carbon dioxide
contained and allow plankton and sea coral to survive.
D. Plankton and sea coral would become extinct because of its inability to make adaptations
fast enough to adjust to the changes in the environment.
SC.7.L.15.3
10. A certain reptile species is an herbivore and exists only on an isolated island. Which of the
following would most likely result in the extinction of the reptile species over a period of
twenty thousand years.
A. The reptile species produces many offspring with some unique traits, and the vegetation
changes slowly.
B. The reptile species produces few offspring with no unique traits, and the vegetation
changes quickly.
C. The reptile species produces any offspring with many unique traits, and the vegetation
remains constant.
D. The reptile species produces few offspring with some unique traits, and the vegetation
remains constant.

Commented [1]: I'm concerned about this question since
the carbon cycle is not addressed until the last unit. Also,
the question has vocabulary such as ocean acidification,
carbonate ions, and carbonic acid which may result in the
students just skipping this question.
