What is an example of osmosis in a living organism?
Fish are the perfect example of osmosis in living organisms. Salt Water fish are constantly drinking because they are always losing water to their environments. On the other hand, fresh water fish almost never need to drink because they are constantly absorbing water through their skin. Could somebody improve this because this doesn't exactly say how osmosis actually happens in living things it just says about salt fish which might have soemthing to do with it/ / Osmosis is when water moves from an area of high concentration to low, which is why salt water fish lose water ( it's less concentrated around them, because of the salt, than in them)
What process is water moving out of the cell of a saltwater fish and into the ocean?
Diffusion is the way water moves out of the saltwater fish and into the ocean.Fish and aquatic animals have a complex task of Osmoregulation. Their bodies and especially the gills are bathed in either salt water with high salt levels for sea life, or freshwater with low salt levels for freshwater fish.The saltwater fish tend to keep saltier blood than freshwater fish. In some species, it essentially matches the environment.In the sea, some animals maintain essentially an isotonic solution between the blood and the salt water thus preventing osmosis into the ocean.Other ocean fish drink salt water, and actively pump sodium and chloride ions out of their gills to maintain the osmotic gradient.Freshwater fish have highly efficient kidneys to excrete lots of water and little salt. However, they still must expend energy to pump salt and ions into their bodies.Here is an excellent summary article:http://www2.hawaii.edu/~delbeek/delb11.html
Name a fish with elastic stomach?
puffer fish
Oak is to trout as tree is to?
fish.
How do fish keep warm?
They have layers of fat, feathers or fur to keep themselves warm. Unlike us, animals have fur so they can keep warm. Take a rabbit for instants, they live in a burrow so they have a warm home.
What are seawater fish?
A seawater fish is a fish that lives in the sea.
Is bluefish a freshwater animal or a seawater animal?

What do seawater fish look like?
There are thousands of species of fish and they all look different from one another in some way. Seawater fish look like fish as do freshwater fish.
Is a lionfish a seawater fish?
yes, it is a salt water fish
What is one way a saltwater fish controls the concentration of salt in its body?
Some fish balance water loss by drinking seawater and actively transporting chloride ions out through their skin and gills then the sodium ions follow passively out as well.
Is a goldfish a seawater freshwater or tropical fish?
Goldfish are freshwater, not saltwater.
Is oxygen soluble in seawater?
Fish and marine life are able to live because oxygen is soluble in water, including salt water/seawater.
Do tropical fish live in seawater?
There are millions of tropical fish in the tropical oceans. But they are all marine fish not freshwater fish. Freshwater tropicals can not live in saltwater.
Seawater that contains a substance that fishes breathe?
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
Would seagull pee dissolve in seawater?
Urine does not dissolve, no. It's there in the seawater along with all the fish urine and seal urine and dolphin urine and pelican urine...
What substance does seawater contain which fish need for breathing?
Basically, gills and oxygen in the water. The fish will die if any one are missing.
How are jawless fish different in addition ways from other fish?
jawless fishes have hyperotonic fluid in their bodies .THE concentration of salt in sea water greater as compare to in their bogies .Jaless fishes secrete some salty secration to make the balance of the concentration of the fluid balance in the body. BUT OTHER FISHES have isotonic fluid to maintain the enternal environment of their body.
