A: 2.37 % (m/v) NaCl Solution: crenation.

B: 0.59 % (m/v) glucose Solution: hemolysis.

C: distilled H2O Solution: hemolysis.

D: 9.39 % (m/v) glucose Solution: crenation.

E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl: neither.

Explanation:

A red blood cell should be placed in an isotonic solution to avoid crenation or hemolysis. An isotonic solution has the same solute concentration as the one in the interior of the cell. As a result, the solvent does not have to move toward the place with a higher solute concentration to balance it.

When the red blood cell is in a solution that has a higher concentration of solutes than the one inside the cell, in other words, the cell is in a hypertonic solution. The solvent will flow from the cell to the solution causing a crenation of the cell.

When the red blood cell is in a solution with a lower solute concentration than the one inside the cell, also known as a hypotonic solution. The solvent will flow from the outside to the inside of the cell. As a result, the cell suffers hemolysis.

The isotonic solution for the cell should be 5.0% (m/v) glucose and 0.9% (m/v) NaCl, to avoid crenation or hemolysis.

In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology.cirrus clouds usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.
