Question

An organism is excreting ions in its urine. What is likely the current tonicity of the

organism's cells, and why?
1.hypotonicity due to too much solute in its body fluids
2. hypertonicity due to less solute in its body fluids
3. hypertonicity due to too much solute in its body fluids
4. hypotonicity due to less solute in its body fluids

Answer 1

The current tonicity of the organism's cells is likely to be hypertonicity due to too much solute in its body fluids.

Step-by-step explanation:

The current tonicity of the organism's cells is likely to be hypertonicity due to too much solute in its body fluids.

According to the concept of osmosis, water tends to move from an area of lower solute concentration to an area of higher solute concentration. In this case, since the organism is excreting ions in its urine, it is losing solute from its body fluids. As a result, the concentration of solutes in its body fluids increases, making the extracellular fluid hypertonic relative to the cytoplasm of its cells. This causes water to move out of the cells, resulting in hypertonicity.
