    • Osmoregulation is the control of water potential in body fluids.
    • Osmoregulation is crucial for maintaining homeostasis in organisms.

      True
    • Match the environment with the osmoregulatory mechanism used:
      Freshwater ↔️ Excrete dilute urine
      Marine ↔️ Excrete excess salt
      Terrestrial ↔️ Reabsorb water in kidneys
    • What is one osmoregulatory challenge faced by freshwater animals?
      Excess water absorption
    • What type of urine is produced by terrestrial animals to conserve water?
      Concentrated
    • What is one importance of osmoregulation for cell function?
      Proper water balance
    • Which osmoregulatory mechanism is used by freshwater animals to excrete excess water?
      Excrete dilute urine
    • Marine animals are at risk of dehydration due to their environment.
    • Freshwater animals excrete concentrated urine to conserve water.
      False

    • What term describes the process by which organisms maintain water and salt balance to thrive in their environment?
      Homeostasis
    • What is the primary risk faced by marine organisms in osmoregulation?
      Dehydration
    • Match the environment with its osmoregulatory challenge:
      Freshwater ↔️ Tendency to absorb excess water
      Marine ↔️ Risk of dehydration
      Terrestrial ↔️ Water loss via evaporation
    • What role do excretory systems play in osmoregulation?
      Maintain water and salt balance
