Answer
Genotype
Question
What type of environment would this snake most likely be able to
survive and reproduce in?
Answer
Desert environment due to the brown color so that it may be able to
camouflage itself. Environment where are easily accessible prey

Question
The uppercase letter W represents the dominant allele for white wool
in sheep. The recessive allele for black wool is represented by the
lowercase w. All the offspring of two sheep are black. What are the
genotypes of the offspring?
Answer
ww
Question
L- is dominant for long eyelashes
l- is recessive for short eyelashes
Which scenario shows the best chance of the offspring having short
eyelashes?
1.) Ll x Ll ( no homozygous parents)
2.) LL x Ll ( one homozygous parent with dominant trait)
3.) ll x Ll (one homozygous parent with recessive trait)

Scenario 3: ll x Ll (one homozygous parent with recessive trait)
There is a 50% chance the offspring will have short eyelashes.
Scenario 1: There was only a 25% chance of having short eyelashes
Scenario 2: There was 0% chance

Question
Which layer contains the oldest fossils?
Answer
Layer D (Trilobytes)
Question
Which type of fossil evidence
would MOST likely be found for
the organism in the illustration?
A. Fossilized hard parts
B. An imprint of the organism
C. Minerals that replaced the
organism
D. No fossil evidence
Answer
B. An imprint of the organism
Explanation: Due to lack of hard bones, the soft body of the dragonfly
will only leave an imprint.
Question
• How does the fossil record help
us to understand the
development of horses?
Answer
The horse fossil record helps scientist infer which organisms were first
to develop on Earth and how horses have changed over time.
Question
How were humans responsible
for the change in the population
of peppered moths in the
Manchester area of England?
Answer
During the Industrial Revolution
humans built factories that spewed
smoke and coal dust into the air. This
release of soot turned the trunks of
trees from brown to black, this made
lighter colored moths to be more
obvious to birds who ate them. The
black moths were better able to
blend in with the darker tree trunks
and could easily hide from prey and
survive longer to reproduce. This
allowed the population of black
moths to increase and the
population of lighter moths to
decrease.
Question
Which one of Charles Darwin’s
finches do you think would be
best adapted for breaking open
large seeds for food?
Answer
Finch #1 (Ground Finch)- having a
large, wide beak will allow it to
break open large seeds.
Question
Which one of Charles Darwin’s
finches do you think would be
best adapted for eating insects?
Answer
Finch #4 (Warbler Finch)- best
adapted for reaching small insects
in narrow spaces.
Question
Observe the pedigree chart.
What do the shapes represent?
What does having a shaded in/not
shaded in shape mean?
Answer
The shapes represent: Male
(square shape) and Female (circle
shape).
The shapes that are completely
filled in indicates being affected by
the trait. The shapes not filled in
indicate not being affected by the
trait.
Question
This starfish is growing a new arm.
What is the name of this process?
What type of reproduction does
this represent?
Answer
Regeneration
Asexual Reproduction
Question
List 3 biotic and 3 abiotic factors in
this picture.
Answer
Biotic: Moose, trees, grass
Abiotic: dirt, air, snow on the
mountains
Question
Is this dead fish considered biotic
or abiotic? Explain your answer.
Answer
The dead fish is still considered biotic because it was once alive. Biotic
factor is anything that is alive or was once alive.
Question
What is the source that producers get their energy?
Answer
The sun
Question
Identify all of the producers in
this picture.
Answer
1.) Grass
2.) Trees
3.) Lilypads
4.) Flowers
5.) all other Plants
Question
List the consumers in this picture.
Answer
1.) Turtles 9.) Water glider
2.) Deer
3.) Fish
4.) Frog
5.) Dragonfly
6.) Ladybugs
7.) Raccoon
8.) Eagle
Question
Consumers depend on producers because
A. Producers use sunlight to make food
B. Consumers cannot make their own food
C. Some consumers eat only plants
D. Some consumers eat only other animals
Answer
B. Consumers cannot make their own food
Question
This lion is a carnivore. Why would
a carnivore (organism that only
eats meat) depend on producers?
Answer
A carnivore would depend on a
producer because carnivores eat
consumers that eat producers (ex.
Zebra)
Question
Pictured is a Great White Shark
surrounded by smaller fish. The
fish receive protection by being
around the shark, however, the
shark is not affected by their
presence.
What type of symbiotic
relationship is this?
Answer
Commensalism
Question
The Oxpecker bird eats ticks and
other bothersome insects off of
large animals like this.
What type of symbiotic
relationship is this?
Answer
Mutualism- Both organisms benefit. The bird gets a meal and the
animal is rid of the parasites.
Question
A tick is shown attached to an
animal. Ticks are known to drink
the blood of its hosts, while also
causing sicknesses such as lime
disease in the host.
What type of symbiotic
relationship is this?
Answer
Parasitism- one benefits and the other is harmed
Question
What is a habitat?
Answer
It is the natural environment in
which an organism lives.
Question
Which of the following is NOT considered a limiting factor?
A. Water
B. Food
C. Shelter
D. Space
E. Carbon
Answer
E. Carbon
Question
10 lions live in a habitat that has enough water, cover and space to
support 20 lions, but there is only enough food for 10 lions. What is the
limiting factor?
Answer
Food is the limiting factor in this example because the population
wouldn't get any larger. A limiting factor is anything in an environment
that limits the population size of a species.
Question
Which picture is a food chain and
which is a food web?
Answer
Food chain- shows 1 path of
energy flow from producers to
consumers.
Food web- shows all the possible
interconnecting food chains.
Question
Explain the relationship between
the moose and wolf population
size increase and decrease.
Answer
Moose are prey for wolves. In the
early 1960s-1965 there were more
wolves than moose which lead to
wolves either starving to death or
migrating away, which caused the
moose population to slowly increase.
As the wolf population decreased,
more moose were able to survive
and reproduce. The increase in the
moose population allowed more
food for the wolves which in turn
caused more wolves to survive and
reproduce. Thus the wolf population
increasing again. This fluctuation
continues on.
