How a fish that migrate from freshwater to seawater (and/or vice versa) osmoregulate?
Step by step
Solved in 2 steps
- Regarding osmoregulation, what physiological and behavioral changes would occur as a fish migrates from a freshwater stream to the ocean?What is the role of the invertebrate/vertebrate gill in osmoregulation?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.
- Explain and contrast osmoregulation in freshwater and saltwater fish.Compare osmoregulation by (1) sharks versus marine bony fish, and (2) freshwater bony fish and freshwater mosquitoes.Describe the underlying osmoregulation issues that aquatic and terrestrial animals confront, as well as their solutions for overcoming them. Emphasize how their osmoregulatory organs have modified.
- The 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 nephronsWhat are the sources of nitrogenous wastes in animals, and how are these converted and eliminated in the osmoregulatory systems of invertebrates, insects, bony fish, mammals and birds?Define nitrogenous wastes, and list the main types produced in animals.What are some advantages and disadvantages of excreting differenttypes of nitrogenous wastes?
- A marine invertebrate such as the anemone is described as an 1.) Osmoregulator 2.) Osmomanipulator 3.) Osmoconformer 4.) Osmosupressor 5.) Osmodictatordefine the term osmoregulation and why would it be important for living things to be able to osmoregulate their bodies?Describe structure of the nephron. How is the mammalian nephron capable of creating concentrated urine? How does filtration take place?
