Adaptation

• What should you be able to describe by the end of the video?

  How organisms are adapted to their environment
• What are the three types of adaptations mentioned?

  Structural, behavioral, and functional adaptations
• What is meant by an extremophile?

  Organisms adapted to extreme conditions
• Are specific examples of adaptations required in the exam specification?

  No, any living organism can be used
• How are camels adapted to desert conditions?

  They have structural adaptations for heat
• What is a structural adaptation of camels?

  Camels have a hump for fat storage
• How does storing fat in a camel's hump help it?

  It allows heat loss from other body parts
• What is another structural adaptation of camels?

  Thick coat on the upper body
• Why do camels have leathery mouths?

  To eat thorny desert plants for water
• What is the purpose of camels' long eyelashes?

  To keep dust out of their eyes
• How do camels prevent dust from entering their nostrils?

  They can close their nostrils
• What is a functional adaptation of camels?

  They produce concentrated urine and dry feces
• How do camels cope with temperature changes?

  They tolerate large changes in body temperature
• What is a behavioral adaptation of the kangaroo rat?

  They are nocturnal to avoid daytime heat
• Where do kangaroo rats live during the day?

  In burrows underground
• What is a structural adaptation of the arctic fox?

  Thick fur for insulation
• How do the soles of an arctic fox's feet help it?

  They reduce heat loss to ice
• Why do arctic foxes have small ears?

  To reduce surface area and heat loss
• How does the arctic fox's coat help it?

  It provides effective camouflage for hunting
• What adaptation do cacti have to reduce water loss?

  Very small leaves or no leaves at all
• How do cacti catch water after rainfall?

  They have extensive and shallow roots
• What allows cacti to survive long periods without rain?

  They can store water in their stem
• What are extremophiles?

  Organisms adapted to extreme conditions
• Where can extremophiles be found?

  In deep-sea vents with harsh conditions
• What conditions do extremophiles tolerate?

  High temperatures, pressures, and salt concentrations
• What type of questions can you find in the revision workbook?

  Questions on adaptations
• What are the types of adaptations organisms can have?

  • Structural adaptations: body shape or structure
  • Behavioral adaptations: lifestyle or behavior
  • Functional adaptations: body functions
• What adaptations do camels have for desert survival?

  • Structural: hump for fat storage, thick coat
  • Functional: concentrated urine, tolerate temperature changes
  • Behavioral: none mentioned
• What adaptations do arctic foxes have for cold survival?

  • Structural: thick fur, small ears, furry soles
  • Functional: effective camouflage for hunting
  • Behavioral: none mentioned
• What adaptations do cacti have for dry conditions?

  • Structural: small or no leaves, spines
  • Functional: extensive shallow roots, water storage in stems
  • Behavioral: none mentioned
• What are the characteristics of extremophiles?

  • Adapted to extreme conditions
  • Can tolerate high temperatures, pressures, and salt concentrations
