Parents/Guardian –
 I have reviewed my child’s activities and
homework for the week of 3/23/093/27/09.
 My child is prepared for the exam on 3/24/09,
and has completed all assignments this week.
 Thursday 3/26 is the spring Open House. As a
member of the Geo Academy I have to
attend a meeting and will not be present.
Please contact me at 286-1275 to schedule
an individual appt. The Open House will be
held around the pool 6-8 pm. Other science
teachers will be available to answer general

Review Questions Caytonia is an extinct plant that existed between 200 and 140
million years ago. It had reproductive structures that
resemble structures in modern flowering plants.
How do scientists know about the structures of this ancient
extinct plant?
A. Scientists study the DNA sequences of Caytonia.
B. Scientists genetically engineer modern plants to
produce Caytonia.
C. Scientists excavate and examine the fossilized
remains of Caytonia.
D. Scientists observe the adaptations of plants in
habitats resembling those of Caytonia.
In a mouse population inhabiting a grassland area, a mutation
occurs that results in a new coat color allele.
Which of the following factors has the greatest effect on
whether the new coat color will become more
common in the mouse population?
A. whether abundant food is available in the
grassland
B. whether the new coat color allele is dominant or
recessive
C. whether the rate of reproduction in the mouse
population is stable
D. whether the new coat color allele increases the
survival of mice in their environment
Similar structures are present in the embryos of fish,
chickens, and rabbits. In fish, these structures
develop into gills, but in chickens and rabbits, they
either disappear or develop into other body parts
later in embryonic development.
Which of the statements below best explains the presence of
these structures in the embryos of all three species?
A. The embryos of the three species are similar in size.
B. Breathing structures are similar among the young of the
three species.
C. The three species have a common ancestor with these
embryonic structures.
D. The reproductive mechanisms are similar among the
adults of the three species.

Monday – The illustrations below show a South American finch and some of the species of finches found on the
Galápagos Islands. The map shows the relationship of the Galápagos Islands to the west coast of South America.
There are 13
species of
finches found on
the Galápagos
Islands. These
finches have a
wide variety of
food sources and
beak shapes.
There is one
genetically
similar species
of finch found
on the South
American
mainland. This
finch eats small
seeds.
Use the map and
the bird
illustrations to identify and explain two ways that these finches provide evidence that supports the
theory of evolution.
European rabbits were introduced to Australia in 1859. The rabbits reproduced rapidly in their new habitat,
displaced other animals, and overgrazed vegetation. In an attempt to reduce the rabbit population, a
virus was introduced in 1951. This virus is usually deadly to European rabbits.
When the virus was first introduced, the rabbits died in large numbers, but the death rate decreased over time.
Which of the following best explains the decrease in the rabbit death rate?
A. Young rabbits learned to avoid being infected with this virus.
B. Natural selection favored rabbits that are resistant to this virus.
C. The lifespan of this virus is too short to affect rabbits over a long period of time.
D. The rabbits that were originally infected with this virus have been dead for many years.
Tuesday –EXAM
Wednesday – EXAM
Thursday - Which of the following is a main function of the cell wall?
A. to store carbohydrates for later use
C. to package proteins for export
B. to give the cell a rigid structure
D. to carry out photosynthesis
Friday - Which of the following best describes the formation of a zygote?
A. A sperm cell nucleus and an egg cell nucleus fuse.
B. A cell’s DNA replication and mitosis are accelerated.
C. A succession of cell divisions produces a solid mass of cells.
D. A cell with 46 chromosomes divides to form cells with 23 chromosomes each.
