Question

If a marine fish is placed in a freshwater aquarium, will the fish be able to survive? Why or Why not?

Answer 1

Hint:Seawater is hypertonic to the fishes living in the sea, which implies that water is constantly being drained out of their bodies. To endure, saltwater fishes constantly drink loads of water to make up for water misfortune brought about as a natural side effect. They sift through abundance salt from their circulation system through their gills and kidneys by urinating.

Complete answer:
There are a wide range of parts that make up marine life's natural surroundings. Some of them are the temperature of the water, the quality, and amount of water (stream and profundity). Different parts that can likewise add to the natural surroundings of saltwater fish are pH level, salt level, and alkalinity level. Most fish that live in the sea will in general lose water, the high salt concentration of the sea makes water continually stream out through the fish's gills and in light of the fact that seawater is so pungent, they likewise should siphon out the abundance salt, both through their kidneys and utilizing specific cells in their gills. On the off chance that a marine fish is placed in a water aquarium, at that point its chance of survival will decrease. This is on the grounds that their bodies are adjusted to high salt concentrations of the marine climate. In new water conditions, they can't control the water entering their body (as a natural by-product). Water enters their body because of the hypotonic climate outside. This outcomes in the expanding of the body, inevitably prompting the death of the marine fish. Because of assimilation, fishes need to osmoregulate, the way toward keeping up a perfect measure of water in their bodies. A few fishes need to drink water, however all need to urinate frequently. Freshwater fish and saltwater fish get by as per how much saltiness their body can continue.
To get this, we should know about few things:
>Osmosis: Osmosis is the development of fluid atoms through a semipermeable layer from a low thought solute to a high focused solute.
>Hypertonicity is brought about by a higher substance fixation outside the cell than within it, and this results in the cell contracting since water streams out of the cell to weaken the substance outside.
>Hypotonicity, then again, is brought about by the high substance focus inside the cell, making the cell swell and burst since water continues streaming in to weaken the cell's answer.
>Fish bodies are hypertonic yet when water moves to an aquarium it gets hypotonic. They can't direct the metabolic cycle in the changed climate and they pass on. Subsequently, from this we accept that the fish from the marine water whenever set in freshwater won’t have the option to endure and will die.

Note:There are some types of fishes who can make due in both freshwater and saltwater. The types of fish, called euryhaline fish, can endure and relocate in the two waterways at or for a specific measure of time, Anadromous fishes are conceived in freshwater, yet burn through the vast majority of their lives in the sea, just getting back to freshwater to lay their eggs, e.g. striped bass, sturgeon, smelt, and salmon.
