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.

With
the rise of international conflicts around the world in the 1930s,
Congress passed the Neutrality Acts of 1935, 1936, and 1937 (49 Stat.
1081, 49 Stat. 1152, 50 Stat. 121).These laws required
registration and licensing by a National Munitions Control Board of all
persons trading in munitions and a mandatory embargo on the export of
arms, ammunition, and implements of war, and on loans
and credits to all belligerents or to neutrals for transshipment to
belligerents. An embargo would take effect when the president found a
state of war to exist.
<span>Today not very well. With the ability to influence with large amounts of power and wealth the structure of Congress has few tools left to protect from this. Public passion is how Democracy works but it has been bought off in a large way today on both sides of the isle. Small states actually have an advantage with more representation per constituent. This is due to the structure of 2 Senators from each state.</span>
Answer:
Prospective study is the correct answer.
Explanation:
Serve as a Symbol of leader ship but ultimately the mayor has no formal authority outside the council The mayor cannot directly appoint or remove officials lax veto power over Council votes.
