Take a fresh grape fruit and keep it in distilled water for an hour. it is stouter than before. Another fresh grape kept in salty water for an hour will appear slim and wrinkled. The grape has dissolved minerals, sugars and other ingredients in its juice. The skin of the grape is a semi permeable membrane across which water can diffuse from one side to the other through osmosis.
When the grape is kept inside distilled water, the concentration (salinity) of juice in the grape is higher than that of water and water moves somatically from outside the grape to inside. Hence the grape appeared stouter. the reverse happened in the case of salty water.
The skin of the fish is like the skin of the grape fruit. If the fish is in distilled water, there is an osmotic flow of water from outside the fish to the inside because the salinity of the fish body is higher than that of water. Thus there is danger of dilution of the body fluids of the fish or at worst that of being blown out if the fish is to be in distilled water for a very long period of time.
Changes away from the ideal salt concentration of the fish causes problems with cellular processes, resulting in an inability to maintain homeostasis, and eventually that will mean either illness or death if the salt balance is not returned to normal.
What else can I help you with?
What are water breathing fish called?
fishes. All fishes breath in the water. They cannot survive outside of water except for few fishes which have adapted to breath air like the mud skipper fish. The only reason fishes are able to breath under water is because of their gills
How are fishes able to get oxygen from water?
gills
Does yeast ferment distilled water?
No, yeast requires sugar to ferment and produce alcohol. Distilled water does not contain any sugars, so yeast would not be able to ferment it.
Does technology affect nature in a good way?
Both yes and no. Yes because if we didn't have the ability to control water temperature through technology, some fishes would not be able to survive. And no because every time we drill for oil in the ocean millions of fishes are in danger.
Can you buy distilled water at tesco banbridge?
Tesco sells several brands of distilled water. This includes Tesco Still Water, Aqua Pura Still Water, Buxton Natural Still Water, and Clearview Still Spring Water.
what is the function of fishes scales?
to be able to live in salty water without the skin melding.
Does a plant grow better watered with well water distilled water or tap water?
Tap water. Distilled water contains no salts and therefore no nutrition for the plant. In reality distilled water would not be able to be absorbed by osmosis into the root system of the plant - as osmosis relies on the differences in concentration of minerals dissolved in the water to work.
What must a plant do to survive on land?
it must have water and soil to be able to survive
Why do you need water to be able to survive?
We don't try it
What must a spices be able to do in order to survive and reproduce?
A species must be able to find food, shelter, and water in order to survive and reproduce. Until a species is able to meet its essential needs, it is not able to reproduce and survive.
Why is it important to be able to tread water?
You will be able to survive for longer than just standing there
How long can spiders survive without water?
Spiders can survive for several weeks without water, as they are able to get moisture from their prey and the environment.
