- What are the osmotic challenges faced by marine animals like fish? Describe how they cope with these challenges to maintain solute and water balance in their tissues.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?If you Ingest excessive amounts of saltwater, you would eventually experience dehydration and die. How do Marine Organisms survive in a saltwater environment?
- what is osmotic pressure ? Why it is helpful ?How is it possible that some species of frogs can brood their eggs and larvae in their gut without being digested or excreted? What examples of physical and chemical barriers protect immobile eggs against predators ?A freshwater fish was accidentally placed in salt water. After several minutes in the saline water it died. What is the most logical explanation for its death?
- why would you expect an animal that lives in fresh water to have a well developed excretory systemBoth saltwater and freshwater fish have adaptations to control the movement of water and salts across their external surfaces. Describe what would happen without these adaptations.There are two types of nephrons. Name them?
