cell, divides it
twice, forming 4
haploid cells
(cells with ½ the
chromosomes).
The image on the right
shows DNA replication,
which occurs during
Interphase.
FALSE!!!!
The Correct Answer is…
The image on the right
shows crossing over, which
occurs during meiosis I in
prophase. It provides for
variation in sexual
reproduction!
The karyotype shows
Down Syndrome which
occurred because the
parents carried a
dominant allele for
the disorder.
FALSE!!!!
The Correct Answer is…
The karyotype shows

inheritance where one trait is not
dominant over another (so two
traits show up). For example,
offspring from a white rabbit and
brown rabbit turn out brown and
white.
TRUE!!!!
The Correct Answer is…
Codominance is a type of inheritance
where one trait is not dominant over
another (so two traits show up). For

carries colorblindness and
has a child with a man
without colorblindness.
There is no chance their
children will have the
disorder.
FALSE!!!!
The Correct Answer is…
The nucleus physically
controls what enters and
leaves the cell.
FALSE!!!!
The Correct Answer is…
The cell membrane (or plasma membrane)
physically controls what enters and leaves

wiped out by the pesticide
when it is reapplied.
FALSE!!!!
The Correct Answer is…
A population of 100 caterpillars is
sprayed with a pesticide. 10 survive
and reproduce. These 10 survived

pesticide is reapplied.
Some diseases, like cancer
and heart disease are
caused by genetic and
environmental factors.
TRUE!!!!
The Correct Answer is…
Some diseases, like cancer and heart
disease are caused by genetic and

can possibly push off the onset of these
diseases.
Transcription is when a
human gene is placed into a
bacterial cell (plasmid) and
the human DNA gets
incorporated into the
bacteria.
FALSE!!!!
The Correct Answer is…
Transformation is when a human gene is
placed into a bacterial cell (plasmid) and
the human DNA gets incorporated into
the bacteria.
Genes to make products humans need,
like growth hormone or insulin are often
made this way.
After an egg is fertilized it
goes through the following
stages of development:
Zygote → Blastocyst →
Embryo → Fetus
TRUE!!!!
The Correct Answer is…
After the egg is fertilized (its called a zygote)
the cell begins to divide and differentiate (turn
into) a hollow ball of cells (called a blastocyst).
Then, it further differentiates into an embryo
as it turns certain genes on to make certain
structures (eyes, hands, heart, etc.). When it
has all parts found in an adult is called a fetus.
In estivation organisms
escape very hot conditions
by seeking shelter and
going into a state of rest. It
is the opposite of
hibernation.
TRUE!!!!
The Correct Answer is…
In estivation organisms escape very hot
conditions by seeking shelter and going
into a state of rest. It is the opposite of
hibernation.
•Hibernation is state of rest to escape
the cold, until more favorable food
conditions exist in the spring.
Birds migrate south in the
fall, going to more favorable
conditions (plenty of food
and warm temperatures).
This is a learned behavior.
FALSE!!!!
The Correct Answer is…
Birds migrate south in the fall, going to more favorable
conditions where there is plenty of food and warm
temperatures. This is an innate behavior.
•Innate behaviors are there when an organism is born
(crying, blinking, suckling, migrating, etc.)
•Learned behaviors must be taught, and occur in organisms
with complex brains. (example - teaching a wolf cub to
hunt, practicing by play fighting, etc.
When a scientist named Pavlov fed his
dogs he rang a bell each and every time.
His dogs came to associate the sound of
a bell with food. Anytime they heard a
noise resembling a bell they started to
salivate (drool). This kind of learning,
where two unrelated things are
associated with each other is called
imprinting.
FALSE!!!!
The Correct Answer is…
When a scientist named Pavlov fed his dogs he rang a bell each and every
time. His dogs came to associate the sound of a bell with food. Anytime
they heard a noise resembling a bell they started to salivate (drool). This
kind of learning, where two unrelated things are associated with each
other is called conditioning.
Types of learned behaviors:
•Conditioning – when an organism learns to associate 2 unrelated things
(Food and a ringing bell.)
•Imprinting – learning to recognize someone or thing as “mother” (as in
Conrad Lorenz’ ducklings did).
•Habituation – where an organism learns to ignore a harmless stimulus
over time (like crows and a scarecrow in a field)
As you move up a food
chain or food web the
amount of energy available
at higher trophic (feeding)
levels is reduced.
TRUE!!!!
The Correct Answer is…
As you move up a food chain or food web
the amount of energy available at higher
trophic (feeding) levels is reduced.
As you move up each step only 10% of the
energy is transferred to the next level. 90%
is lost through life processes (movement,
respiration, reproduction) as heat.
Global warming is the
natural heating of the Earth,
caused by the trapping of
heat and water vapor in the
atmosphere.
FALSE!!!!
The Correct Answer is…
The Greenhouse Effect is the natural
heating of the Earth, caused by the
trapping of heat and water vapor in the
atmosphere.
