- What are the three types of nitrogenous wastes? Which animals aremost likely to excrete each one, and why?Draw a labelled diagram of excretory system of "common carp" fish?I know marine mussels are osmoregulators but if you but them in a very very very salty enviorment would it bad for them or would they still be okay?
- Explain and contrast osmoregulation in freshwater and saltwater fish.In the aquatic world, osmoregulation is very important. Please describe what would happen at the cellular level as well as organismal level to a freshwater fish that is placed in salt water.Describe one adaptation for osmoregulation in freshwater animals, saltwater animals, and saltwater plants.
- Regarding the function of nephrozoan nephridia, would you expect the final urine of a freshwater species to contain more or less water than the final urine of marine species? Explain.Which of the following animals generally has the lowestvolume of urine production?(A) vampire bat(B) salmon in fresh water(C) marine bony fish(D) freshwater flatwormWhat is the role of the invertebrate/vertebrate gill in osmoregulation?
