Questions and Answers

How do freshwater fish achieve osmoregulation?

  • Increased water uptake through the gills
  • Passive reabsorption of ions in the kidneys
  • Production of concentrated urine to conserve water
  • Specialized ion transport mechanisms in the gills (correct)

    • What is a challenge faced by freshwater fish in osmoregulation?

  • Preventing excessive water uptake (correct)
  • Maintaining high solute concentrations in the body
  • Producing concentrated urine
  • Reducing ion absorption in the kidneys

    • What is a key feature of osmoregulation in fish?

  • Active reabsorption of ions in the kidneys
  • Passive excretion of excess water through the skin
  • Specialized ion transport mechanisms in the gills (correct)
  • Production of concentrated urine to remove excess water
