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.

President Roosevelts domestic policy was called the "Square Deal"
Answer:
Fitness, a fundamental concept in evolutionary biology, is defined as reproductive success/number of offspring, or as adaptedness, that is, properties and capacities that make an organism more adapted to the environment.
Explanation:
I believe the answer is: artificial intelligence (AI)
Currently, machineries have replace a lot of jobs that usually done by humans. But all of those only the jobs that are repetitive and simple. artificial intelligence (AI) on the other hand is capable to perform complex decision making like humans do (even better than most people).
