Based on the demonstration and your microscopic investigation, which of the three solutions is hypotonic to the red blood cells?
r-ruslan [8.4K]

You have given no demonstration based on your microscopic investigation so I cant tell you the answer to the question. I will try to help you by elaborating how to decipher..

Three terms hypotonic, hypertonic and isotonic are used when referring to two solutions separated by a selectively permeable membrane.

The hypertonic solution has a great concentration of OAS than the solution on the other side of the membrane. It is described, therefore, as having a great osmolarity. The hypotonic solution has a lower concentration of OAS, or osmolarity, than the solution on the other side of the membrane. When the two solutions are at an equilibrium, the concentration of OAS being equal on both sides of the membrane, the osmolarities are equal and are said to be isotonic.

The net flow of water is from the hypotonic to the hypertonic solution. When the solutions are isotonic, there is no net flow of water across the membrane.

If red blood cells are placed in a solution with a lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell; such a solution is hypotonic to the cells.

So, look at the information and data you have on your microscopic investigation and use these guidelines to tell you which is which.

vekshin1

Answer:

Upwelling

Explanation:

Upwelling is the process through which cold water gets to ascends from the bottom, providing nutrients to the superficial stratum.

Upwelling is an ascending displacement of marine currents. The phenomenon<em> can also occur in lakes or freshwater dams</em>.

Wind blowing over the coast can cause surface water to move out to sea. This motion is complemented by a slow ascension of cold water coming from the bottom forward to the coast. This currents movement is known as upwelling.

Upwelling water is extremely cold and rich in nutrients, which result from remineralization, by bacterial action, of organic matter that accumulates in the deepest stratum of the water body.

The contact of minerals with photosynthesizing organisms in superficial layers produces a significantly high primary productivity.
