burying themselves in the bottom of ponds before they freeze over
American Toads
A Polar Bear is very large and rotund (round). This shape conforms to:
Bergmanns Rule

Bergmanns rule
Bitterns have stripes on their breasts that background match in their habitat
F
Porcupines have quills coated with antibiotics and can shoot them up to 1 metre.
F
The best colour for animals living in cold, northern regions is black.
F
birds are the only animals that migrate
F
Autotomy is the ability to shed a body part and regrow it. This is a defence of:
Five lined Skinks
sticking out a bright red osmetarium from their head (to look like a snake) is a secondary defence of what
Giant Swallowtail
Animals in northern areas tend to be paler than animals farther south. This principle is known as:
Glogers
Animals in northern areas tend to be paler than animals farther south. This principle is known as:
Glogers Rule
Freeze tolera animal
Gray Tree Frog
W
M
allowing its body temperature to rise to a hyperthermic level
Mourning Dove
When several unrelated animals all possess a powerful defence and all look alike, the principle is known as:
Mullerian Mimicry
a number of animals, non-related and all armed with some defence, look like each other
Mullerian Mimicry
the new world champion migrants for both distance and endurance (non-stop flight)
Red Knots
allowing some of the intercellular (between cells) water inside their body to turn to ice
Spring Peepers and Wood Frogs
Black Fly larvae attain food by using labral brushes to filter-feed in flowing water
T
Female Photuris fireflies sequester their toxins from male Photinus fireflies.
T
Giant Swallowtail caterpillars use masquerade as their first defence
T
In winter evergreen ferns curl their leaves to avoid desiccation (by reducing the surface area)
T
Mallards (ducks) are able to see behind their heads and in front of them at the same time
T
Migration is studied by banding birds. Before they are banded, songbirds are captured in mist nets.
T
Skunks are black and white because this colour pattern makes them better camouflaged for night activity.
T
Snakes spend winter deep in the ground, beneath the frost line, in hibernacula
T
The tapetum lucidum is an adaptation for seeing at night.
T
Virginia Opossums play dead when frightened:
T
Yellow Warblers migrating to warm, southern areas
T
plants that are cold hardy add antifreeze into the cells of their tissues to lower their freezing point
T
the first stage of becoming cold hardy involves the photoperiod
T
Purpose of they taste bitter and thus serve to deter an animal from eating a plant
Terpenoids
modified branches Correctyou didn't get stuck by this one
Thorns
raising itself higher off sand by stilting its legs to stay cool
Tiger Beetle
Plants become cold hardy by this process:
acclimation
American Bitterns have streaks down their breast because the stripes: a. are a type of masquerade b. allow a bittern to hide in cattail marshes c. make the bittern look larger (taller) than it really is d. make bitterns blend into a forest with vertical tree trunks e. are disruptive patterns for camouflage Incorrect
allow a bittern to hide in cattail marshes
Bright colours worn by insects that are poisonous are known as:
aposematic colouration
if you see a caterpillar covered in yellow and red spines, you would suspect that it:
background matching
An insect eats a plant and continues to stay in its juvenile state and cannot change into an adult. It likely ate:
balsam fir
add lots of mud to the outside of their lodge for insulation
beaver
Insects that swim at the surface of ponds often have this defence
bicolouration
Insects that swim at the surface of ponds often have this defence:
bicolouration
When frightened, a Killdeer "freezes" and allows this adaptation to help protect it:
breast bands for disruptive colouration
When Underwing Moths open their wings, this happens
bright patterns startle a predator
When small birds find an owl, they often do this:
cryptic and background matching
Flocking in birds offers this benefit: Select one: a. birds never get lonely b. birds do not get lost c. flocks are able to find food more easily d. a flock provides more eyes to watch for danger and lessens the odds of being caught for each bird in the flock
d
Chipping Sparrows have a black line through the eye and a white stripe above it. These marks are called:
disruptive patterns
shunting more blood into its abdomen to stay cool
dragonfly
The most common cryoprotectant used by animals is:
glycerol
Gulls, ducks, and geese can stand on ice without freezing their feet because of this adaptation:
heat exchangers
Bird that migrates during the day
hummingbirds
Moose solve the winter mobility problem by:
long legs
Inchworm caterpillars looks like twigs. This defence is known as
masquerade
Songsbirds fly during the day or night
night
What would happen if a plant which x chemical moult too often and and transform into its adult stage too early and die prematurely
phytoecdysone
If an insect eats Balsam Fir, it never matures into the adult stage because it ingests a lot of this chemical defence:
phytojuvenile hormone
When Hog-nosed Snakes are frightened, they do this:
play dead
Monarch butterfly caterpillars are not good to eat because they contain cardiac glycosides (terpenoids). They get these by eating milkweed leaves. The way they acquire the toxins is known as
sequestering
Black-capped Chickadees conserve energy on cold nights by using
shelter
A moth sits camouflaged on a tree trunk. When disturbed, it opens its wings and two large eyespots appear. These:
startle predator
small mammals such as meadow voles in winter have importances to
subnivean space
Black-capped Chickadee lowers its body temperature by 12 deg C and enters a deep sleep is an example of
torpor
Chipmunks and Raccoons escape cold temperatures by:
torpor and lethargy
