2.6 Adaptations

• What is an adaptation in biology?

  Inherited trait for survival
• The beak shape of finches is an example of a structural
• What type of adaptation is the migration of birds?

  Behavioral
• Camouflage in chameleons is an example of a physiological adaptation.
• Match the type of adaptation with its example:

  Structural ↔️ Beak shapes in finches

  Physiological ↔️ Camouflage in chameleons

  Behavioral ↔️ Migration of birds
• What are the two primary mechanisms of adaptation?

  Natural selection and mutation
• Order the following examples of adaptations by their type:

  1️⃣ Webbed feet of ducks

  2️⃣ Hibernation of bears

  3️⃣ Migration of birds
• The hibernation of bears is an example of a physiological
• What two processes are essential for the long-term survival and evolution of species?

  Natural selection and mutation
• Structural adaptations, such as the webbed feet of ducks, enhance their ability to swim.
• Hibernation in bears is a behavioral adaptation.

  False
• What behavioral adaptation do birds use to relocate to warmer climates for breeding and feeding?

  Migration
• An adaptation is an inherited trait that enhances an organism's survival and reproduction in its environment.
• Match the type of adaptation with its example:

  Structural ↔️ Beak shapes in finches

  Physiological ↔️ Camouflage in chameleons

  Behavioral ↔️ Migration of birds
• Structural adaptations involve changes in bodily processes.

  False
• What is an example of a physiological adaptation in chameleons?

  Camouflage
• The migration of birds is an example of a behavioral adaptation.
• Order the processes of natural selection and mutation in adaptation:

  1️⃣ Mutation introduces new genetic variations

  2️⃣ Natural selection favors beneficial traits

  3️⃣ Advantageous traits are passed to offspring

  4️⃣ Frequency of beneficial traits increases
• Natural selection provides new genetic material for adaptations to occur.

  False
• Match the species with its adaptation and function:

  Polar bear ↔️ Thick fur

  Camel ↔️ Water storage in humps

  Monarch butterflies ↔️ Long-distance migration
• Genetic variation within a population is essential for natural selection to drive adaptation and biodiversity.
