Adaptations and Structures

Adaption can mean several things. Please select the correct ways it is used.

• Process that occurs over time and generations to allow organisms to adapt to their environment.

• A trait (gene) that developed over time and generations

• The amount of fitness an organism has inherited to fill a niche

• A trait gained after birth in a single organism which is not genetically linked.

An example of a behavioral adaptation is

• The long neck of a giraffe
• Penguins huddling together for warmth
• A camel's hump used to store water
• A polar bear's white fur used for camouflage

An example of a physical adaptation is...

• a turtle hiding inside its shell
• The spikes on a porcupine fish
• a rabbit burrowing underground
• a viper biting when threatened

A monkey has a long tail to help it swing from branch to branch in a dense forest.

Hummingbirds have a beak just the right length to reach the nectar in a cardinal flower and as they feed their foreheads bump into the pollen structure. Cardinal flowers are red which hummingbirds can see but bees can’t. Cardinal flower’s pollen structure is just the right length for the hummingbird to pick up pollen as it feeds. This is an example of which type of Evolution

• Convergent

• Divergent

• Co-evolution

In the ocean surrounding Antarctica, there are fish that survive the cold water by using a molecule made of glycoproteins that circulates the blood and keeps it from freezing. Certain kinds of worms that live in the Arctic ocean also make antifreeze proteins that help them live in icy water. This is an example of which type of evolution?

• Convergent Evolution

• Divergent Evolution

• Coevolution

Whales, sharks, and penguins all have streamlined bodies and fins/flippers for moving in water even though they belong in different classes of animals (mammals, fish, and birds) and are not closely related. This is an example of which type of structure?

• Analogous

• Homologous

• Vestigial
