Lesson 1
A change in structure, function, or behavior that helps an organism survive and reproduce.
Adaptation
Color or body structure that blends with the background.
Camouflage
An inborn automatic response, like blinking.
Reflex
Stems of cacti store this.
Water
An animal with fur or feathers controls body heat this way.
Endothermic
A difference in structure, form, or function within the same species.
Variation
Bright colors that signal danger or poison.
warning colors
An inborn complex behavior pattern, like turtles returning to lay eggs.
Instinct
Roots that act like stilts and filter salt in mangroves.
Aerial roots
Which plant reproduction method uses sideways stems to make new plants?
Runners
Charles Darwin studied these birds on the Galápagos Islands.
The Finches
The swallowtail butterfly caterpillar looks like bird droppings.
mimicry
Resting state in winter that slows body functions.
Hibernation
Plant growth response toward light.
phototropism
Animals that lower their body temperature, heart rate, and breathing rate to become inactive in winter.
Hibernation
During drought years, which finches survived better—small-beaked or large-beaked?
large-beaked finches
The mosquito has this type of mouthpart for feeding on blood.
piercing mouthparts
Resting state that helps animals survive dry conditions.
Estivation
Modified leaves that trap insects for nutrients.
Carnivorous plant leaves
A non-poisonous scarlet king snake looks like the poisonous coral snake.
Mimicry
Which theory said animals could purposely change themselves, such as giraffes stretching their necks
Lamarck’s theory
What adaptation does a Cheetah use to catch Prey
Running Fast
Moving from one place to another for survival.
Migration
A plant that folds its leaves when touched.
Mimosa
The mimic octopus avoids predators by doing this.
Change color and shape to copy other animals
