The right answer is E. Sodium  (with 140mmol/L)

Sodium is the most important element in the blood and extracellular liquids of the body.The needs of an adult subject are of the order of 1 to 2 g of sodium per day. The normal diet is much richer than our actual needs, about 4g, so it can largely compensate for the needs of an athlete or a runner.
Losses are majoritarly by feces and sweat. The kidney is able to reabsorb almost all the sodium that is filtered: urinary losses can be tiny.

In an investigation, plant cells are placed in water that has been tinted blue. The investigators observe the color of the cells
larisa [96]

Answer:

C

Explanation:

When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.

If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.

In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.

Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.

The amount of water in each body compartment mainly is controlled by
Elis [28]

The<u> ion concentration</u> in water molecules controls the amount of water in a compartment

The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.

Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.
