Biology Class: Adaptations Quiz

Study Notes

Physical adaptations are adjustments to internal or external structures.
Examples include fur color, long limbs, strong jaws, ability to run fast.
These help organisms survive in specific environments.
Ducks have webbed feet to aid swimming.
Cacti have thick, waxy cuticles to conserve water.
Turtles have hard shells for protection.
Sharks have an excellent sense of smell and sharp teeth.
Pufferfish have spines and can fill their bodies with air or water.
Roses have thorns (modified leaves).
Structural adaptations involve parts of an animal's body, including teeth, body coverings, and movement.

Behavioral adaptations are adjustments in an organism's behavior.
Wolves traveling in packs, schools of fish, and symbiotic relationships are examples.
These adaptations help animals survive seasonal climate changes.
Migration and hibernation are examples of behavioral adaptations.
Behavior adaptations can be learned or instinctive.
Social behaviors and behaviors for protection are examples of behavioral adaptations

Adaptions for movement include the ability to move on land, in water, and in the air.
Features for breathing underwater include skin, gills, gill chambers, air tubes, air bubbles, special nostrils, and blowholes.

Body coverings, poisonous skin, appearing bigger, camouflage, and mimicry are examples of adaptations for protection.

In animals, adaptations include body covering, lighting up, and behavioral changes.
In plants, adaptations for reproduction are not specified.

Adaptations allow animals to cope with the temperatures of their environment, including hot and cold environments.

Migration is a behavioral adaptation.
Animals migrate for various reasons, including better climate, better food, a safer place to live, raising young, and returning to their birthplaces.

Hibernation is a deep sleep during which an animal's body temperature drops and body activities slow to conserve energy.
Bats, woodchucks, and bears are examples of animals that hibernate.

Angiosperms have scented flowers to attract pollinators.
Orchids have adaptations to survive wet, hot temperatures, including pseudobulbs, aerial roots, and drip-tip leaves.
Cacti have thick, waxy stems and dense, shallow roots.

Camouflage is a protective coloration and resemblance that allows an animal to blend into its environment.
Mimicry is the close external resemblance of an animal or plant to another animal, plant, or inanimate object.
