The answer is
A. For every
action there is
an equal and
opposite
reaction.
IPC 5A The student is expected to demonstrate wave
types and their characteristics.
Click on screen for answer
You observe a pulse
in someone’s neck
and again in their
wrist.
This would be an
example of what
type of wave?
A. Transverse
B. Longitudinal
C. Surface
D. Electromagnetic
The correct answer is A. The skin is
just moving up and down.
Bio 5A: The student is expected to compare cells from
different parts of plants and animals, including roots,
stems, leaves, epithelia, muscles, and bones to show

Bio 5B: The student is expected to identify
cell differentiation in the development of
organisms
Click on screen for answer
How are these organisms
which all start out as a
single cell able to
become so different?
A. Their DNA is different
B. Their cells change as
they develop
C. Both answers are
Fish
Mouse
Pig
correct
D. Neither answer is Answer C is correct. Their cells change as they
correct
develop because their DNA is different.
IPC 5 B: The Student is expected to:
demonstrate wave interactions including
interference, polarization, reflection, refraction
and resonance.
The glare of bright sunlight
on a field of snow is
blinding. Glare is the
result of light:
A. Resonating
B. Refracting
C. Becoming polarized
D. Reflecting and
scattering
Click for answer
The reflecting and
scattering of light
increases glare. Answer D
IPC 6B: The student is expected to: investigate and
demonstrate the movement of heat through solids,
liquids, and gasses by convection, conduction and
radiation.
This buzzard is able to
soar to great heights
because the air gets
heated and rises.
This is an example
of:
A. Conduction
B. Radiation
C. Thermal resonance
D. Convection
Click for answer
The movement of the
heated air is due to
convection. Answer D.
Bio 6D: The student is expected to compare
genetic variations observed in plants and
animals.
In the ear of corn shown below, some of the kernels are dark and some
are yellow. If the alleles for color are (C) for colored and (c) for
yellow, the yellow kernels must be
Click for answer
A. Homozygous dominant
B. Homozygous recessive
The correct answer is B. In
C. Heterozygous
order to show the yellow
D. Mutants
color both alleles must be
recessive
Bio 6E: The student is expected to compare the
processes of mitosis and meiosis and their
significance to sexual and asexual reproduction.

answer
The correct
answer is B.
IPC 6F: The student is expected to:
investigate and compare series and parallel
circuits.
You notice that there is a light
on the Christmas tree
which has burned out but
the rest of the strand of
lights is unaffected. This
is an example of:
A. A circuit in series
B. A circuit in parallel
C. A short circuit
D. A fused circuit
The correct answer is A.
Click for answer
If one light is out but the
rest remain on the circuit
is wired in series.

bonded compound
IPC 9A: The student is expected to: relate the
structure of water to its function as the
universal solvent.
Water boils at 100 degrees
Celsius. Why is boiling
water a more efficient
solvent than cold water?
A. The molecules move
faster
B. The molecules have
more energy
C. Both answers are correct
D. Both answers are
incorrect
Click for answer
Heat increases the speed
and energy of the
molecules. The correct
answer is C.
