adaptations to different environments

• what does the type of nitrogenous waste produced by animals link to


  the environment in which they live
• what type of nitrogenous waste do aquatic animals produce


  ammonia
• how do aquatic animals excrete amonia


  from ammonia being very soluble it can diffuse very quickly across the gills of the fish into the water where it is diluted to a non-toxic level
• what are the characteristics of ammonia


  highly toxic and very soluble
• what type of nitrogenous waste do birds reptiles and insects excrete


  uric acid
• what are the characteristics of uric acid


  almost insoluble in water
• what does the excretion of uric acid require


  a lot of energy but not alot of water
• what does the excretion of uric acid not needing a lot of water mean about a birds reptile and insects habitats


  they can survive in dry environments
• what type of nitrogenous waste do mammals excrete


  urea
• what is more toxic ammonia or urea


  ammonia
• what does urea being less toxic then ammonia mean abount how long mammals can store it


  mammals can store for longer
• what does teh excretion of urea require


  a lot of water
• how do dester mammals obtain water


  water will be produced from the breakdown of food during respiration in the cells (metabolic water)
• where may desert animals live to help them survive the heat ,explain why


  underground burrows to reduce water loss by evaporation
• what is the loop of henle concerend with


  water reabsorbtion
• what does the relative loop of henle length adaprt to


  the typical availability of water in its habitat
• would the loop of henle of an aquatic animal reach the medulla, exaplin why


  no because it doesn't need to reabsorb much water
