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.

The term 'invisible hand' was first used by Adam Smith in the 18th century to describe the efficiency in the autoregulation of free markets, where free means not externaly intervened by governments. Intervention distorts markets and harms the efficiency of their functioning.
The main principle behind is that, when individuals pursue their "private" efforts they are generating larger wealth for society as a whole than if their first intention was to help society. The markets will be in charge of channelizing individuals interests into socialy desirable outcomes.

Answer:
Explanation:
Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
Answer:
separation of duties
Explanation:
Here, the case provided of the Radiant company is a simple case of separation of duties as it can strengthen internal control significantly. This separation of duties procedure will ensure that two different departments or at least two different people are responsible for sales and for recording cash transactions. This will reduce the chance of error as the person who made the sale might be careless or overworked in recording cash transaction and can also commit fraud as they are the one who knows the sales amount and can alter the sales details and documents. Hence by separation of duties, internal control will be strengthened.
