Which adaptation (for the underlined animal) serves the function of defense?
A walking stick looks like the twig on which it rests.
A porcupine’s quills cause a predator to seek another meal.
A whale filters plankton and krill from the water in which it swims.
A penguin is dark on top and white below to blend in with the water.
Which of the following is a physical adaptation for the underlined animal?
A butterfly has bright colors to warn predators that it is poisonous.
A hognose snake rolls over, slows its breathing, and hangs its tongue out to play dead.
A herd of buffalo encircle their young to protect them from a pack of wolves.
A dung beetle rolls a piece of dung across the desert.
Which adaptation would NOT help a hawk catch a mouse?

A nice smell is an adaptation that __________________.
helps the plant keep water inside the leaves.
pokes animals that try to eat the plant.
attracts pollinators to the plant.
Where the better adapted organisms survive to pass traits along to offspring.
Evolution
Extinction
Natural Selection
Artificial Selection
The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?
light moth
dark moth
both will be equally successful
neither will be successful
The example of the peppered (brown) moths living near English industrial cities demonstrates that ________.
a change in an environment can result in the evolution of species living there
evolution occurs so slowly that is it not possible to determine that it has happened in less than a million years
the environment near these cities has always favored dark colored moths
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the trait is an acquired phenotype.
The structure of a bird bone (the left side) in comparison to a human bone (the right side) is shown in the image. What is the most likely reason for the difference in the two bones?
A human bone is thicker than a bird bone, allowing for more blood storage.
A bird bone is more hollow than a human bone, giving the bird less mass enabling the bird to fly.
A human bone is less dense than a bird bone, allowing better support of the higher mass of a human.
A bird bone is more dense than a human bone, making it ideal for the upright position of the bird.
What structure is an adaptation for fish that enable the fish to breath by extracting dissolved oxygen from the water?
gills
fins
mucus layer
scales
Organisms have gradually adapted certain structures that help them succeed in their environments. What internal structure have birds developed that helps them successfully fulfill their niche?
oil glands for flight endurance
pointed beaks to increase chances of attracting a mate
hollow bones to reduce mass for flight
webbed feet for landing on tree limbs
Internal structures of organisms have adaptations that enable organisms to be successful in their environment. Blubber in a penguin is one example of this. What function does the blubber perform for the penguin?
make the penguin look bigger to scare off predators
add bulk to the penguin, enabling it to balance on the ice
protect the penguin from freezing water temperature
allows more friction between the penguin and ice
