7.1.3 Adaptations

• Adaptations are the result of natural selection acting on variations within a population over many generations.


  True
• What is an example of a behavioral adaptation?

  Birds migrating in winter
• What is a structural adaptation in cacti that helps them survive in dry environments?

  Thick, waxy stems
• Steps of how adaptations arise through natural selection:

  1️⃣ Variations occur within a population

  2️⃣ Natural selection favors beneficial traits

  3️⃣ Organisms with these traits survive and reproduce

  4️⃣ Over generations, the beneficial traits become common
• Match the type of adaptation with its example:

  Structural ↔️ Polar bear's thick fur

  Behavioral ↔️ Birds migrating in winter

  Functional ↔️ Camels storing water
• The ability of some plants to store water in their roots is a physiological adaptation
• What is a physiological adaptation in snakes that helps them capture prey?

  Using venom
• Structural adaptations are physical features of an organism that help it survive
• What is an example of a physiological adaptation in camels?

  Storing water
• Natural selection allows organisms to better cope with environmental challenges by favoring beneficial adaptations.

  True
• Cacti have thick, waxy stems as a structural adaptation to reduce water loss
• What is an example of a behavioral adaptation in camels?

  Camouflage
• Adaptations in animals enable them to survive and reproduce in specific habitats due to natural selection.

  True
• Natural selection acts on variations within a population to create adaptations over generations.


  True
• What is an example of a behavioral adaptation in birds?

  Migration
• What are adaptations in biology defined as?

  Biological features for survival
• A structural adaptation example is a polar bear's thick fur
• Match the type of adaptation with its example:

  Structural Adaptation ↔️ Polar bear's thick fur

  Behavioral Adaptation ↔️ Birds migrating in winter

  Physiological Adaptation ↔️ Camels storing water
• Birds migrating to warmer climates in winter is an example of a behavioral adaptation
• Natural selection acts on variations within a population over many generations to produce adaptations.


  True
• What is a structural adaptation in desert plants to reduce water loss?

  Small or absent leaves
• Birds' beaks adapted for different food sources are examples of structural adaptations.


  True
• What are biological features that help an organism survive and reproduce in its environment called?

  Adaptations
• Behavioral adaptations involve actions taken by an organism to survive, such as birds migrating to warmer climates.


  True
• Adaptations are the result of natural selection acting on variations within a population
• What are three types of adaptations found in plants?

  Structural, behavioral, physiological
• Categorize the following animal adaptations by type:

  1️⃣ Polar bear's thick fur: Structural

  2️⃣ Birds migrating to warmer climates: Behavioral

  3️⃣ Camels storing water: Physiological

  4️⃣ Snakes using venom: Physiological
• Birds' beaks are structurally adapted for different food sources
• What is the primary role of adaptations in an organism's survival?

  To survive and reproduce
• A polar bear's thick fur is a structural adaptation for insulation in cold climates
• Camels store water in their bodies as a physiological adaptation for water conservation
