Freshwater fish are in a hypotonic environment. "Freshwater fish have chloride cells, which vigorously move chloride ions into gills, followed by sodium ions."
<h3>What is hypotonic environment?</h3>
In biology, the term refers to a cell environment that contains less solute than the cell's cytoplasm.
When a cell is placed in a hypotonic surroundings, osmosis causes a net water flow into the cell, which has the potential to cause the cell to burst and cease functioning.
Solutions and cell surroundings are also classified as hypotonic, hypertonic, or isotonic in terms of osmotic pressure.
Some key features regarding the hypotonic environment are-
- Plants can grow in hypotonic conditions. Their cells have rigid cell walls that keep them from bursting or lysing.
- The cytoplasmic pressure against the cell wall prevents the plant from wilting as well as losing its shape. This is known as turgor pressure and osmotic pressure.
- Cells without cell walls, on the other hand, swell and, if the surroundings is adequately hypotonic, burst (lyse) & die (as to cytolysis).
- Some protists (including such Paramecium) counteract this by using contractile vacuoles, which rapidly pump water out of the cell.
- Other organisms eject solutes from the cell in order to reduce the concentration gradient of a solute in the cell and, ideally, create an isotonic environment. Protists are microorganisms that only exist in hypotonic environments.

Answer:
Industry in backward areas can become very helpful to revitalize the economy and improve the standard of living of the population with the provision of jobs, salaries, and other associated economic activities. So in this sense, establishing industry in backward areas would be necessary and very helpful as well.
However, there is the issue of whether industry can survive in a backward area, or if it can be established there in the first place. Backward areas are precisely backward because they lack certain socioeconomic indicators that attract dynamic economies, like the education level of the population, or economies of scale. For this reason, it is likely that many incentives, like tax incentives, would be needed for an industry to establish itself in a backward area in first place.
