Adaptations
Who designed many adaptations at Creation?
God
Mimicry is this.
Imitation in nature
Behavior is the reaction of an organism to this in its environment.
A stimulus
Plant adaptations include modifications of roots, stems, and these.
Leaves
True or false: All innate and learned behaviors are behavioral adaptations
True
Information in this gives organisms the ability to continue to adapt to changed conditions.
DNA
A special structure or design of an animal or plant part that helps it survive in its habitat is called this.
A physical adaptation
Animals are born with these behaviors, such as reflexes and instinct.
Innate
Unusual scents are a reproduction adaptation that attracts these.
Pollinators
Which is a plant adaptation: seed dispersal or hibernation?
seed dispersal
Any structure, function, or behavior that helps organisms survive and reproduce in the habitats where they live is called this.
An adaptation
What physical adaptation helps a polar bear stay warm in the Arctic?
Thick fur and a layer of body fat.
Animals learn other behaviors from these sources.
Their parents or through experience
What resource do plants need from sunlight to make their own food?
Light energy for photosynthesis.
True or false: Adaptations function only in feeding.
False. They also function in protection, maintaining body functions, escape, and mimicry.
True or false: There is no limit to the amount of change built into the DNA of an organism.
False. There are limits to the amount of change built into the DNA of different organisms.
A porcupine has sharp quills. Is this a physical or behavioral adaptation?
physical
What is it called when birds travel to warmer places during certain seasons?
Migration
These plant parts allow plants to colonize new areas.
Runners
A plant grows toward a window where sunlight enters. What is this response called?
Phototropism
What may happen to a population if its environment changes so much that its inherited adaptations nolonger help it survive?
The population may decrease, move to another area, or become extinct if it cannot adapt or adjust quicklyenough.
A feature or coloration that helps an organism blend into its surroundings.
camouflage
Name three examples of behavioral adaptations.
Any three: hibernation, estivation, migration, communication, tool use, social behavior
Plant tropisms include responses to these three stimuli.
Sunlight, gravity, and touch
Name two ways plant adaptations help plants reproduce.
Any two: unusual scents to attract pollinators, runners to colonize new areas, seed dispersal
