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.
If a kangaroo rat was to drink excessive alcohol, how would that effect him in terms of osmoregulation?
The activity below illustrates the effect of which of the following?
Choose from the following:
(A) concentration osmotic gradient effect without ADH or aldosterone
(B) concentration osmotic gradient effect with aldosterone
(C) concentration osmotic gradient effect with anti-diuretic hormone

- The kidneys of different species of amniotes differ widely in their ability to concentrate the urine. What determines the maximum osmolarity of the urine an animal's kidney can produce? Explain why. (not to long)arrow_forwardWhich mechanism of osmoregulation is shared by sharks and hagfish? the osmolarity of their plasma is about the same as that of sea water both are osmoregulators both excrete all of their nitrogenous wastes as uric acid both drink large amounts of fresh water to avoid desiccation (drying out)arrow_forwarda) The process by which salmon maintain an internal balance is called osmoregulation. Describe how salmon achieve osmoregulation as they migrate between fresh and saltwater environments. b) Describe what happens to salmon in fresh water. What direction do solutes tend to move via diffusion? What direction does water tend to move via osmosis?arrow_forward
- Birds that live in marine environments and thus lack access to fresh drinking water A)obtain water by eating only osmoregulating prey. B)osmoregulate without using a transport epithelium for this purpose. C)drink seawater and secrete excess ions through their kidneys only. D)drink seawater and secrete excess ions mainly through their nasal salt glands. E)have plasma that is isoosmotic to ocean water.arrow_forwardWhy are humans not able to meet their water requirements by drinking seawater? Assume seawater has a concentration of 1400 mOsM. In your explanation, consider both the renal system and the digestive system. Additionally, describe the physiology of two symptoms of excessive seawater consumption that occur prior to death.arrow_forwardWhich of the following statements about osmoregulation is true? a. In freshwater invertebrates, salts move out of the body into the water because the animal is hypoosmotic to the water. b. A marine teleost has to fight gaining water because it is isoosmotic to the sea. c. Most land animals are osmoconformers. d. Vertebrates are usually osmoregulators. e. Terrestrial animals can regulate their osmolarity withoutexpending energy.arrow_forward
- 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?arrow_forwardIn a short essay (100–150 words), compare how membrane structures in the loop of Henle and collecting duct of the mammalian kidney enable water to be recovered from filtrate in the process of osmoregulation.arrow_forwardThe bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsarrow_forward
