In the example provided in question 23, which type of solution is the egg placed in?

Rationale

In the example provided in question 23, the egg is placed in a hypertonic solution.

When an egg is submerged in a hypertonic solution, the concentration of solutes outside the egg is higher than inside, leading to the movement of water out of the egg and causing it to shrink. This process demonstrates osmosis, where water moves from an area of lower solute concentration to an area of higher solute concentration.

A (Hypertonic) CORRECT

This choice is correct because a hypertonic solution has a higher concentration of solutes compared to the inside of the egg. As a result, water flows out of the egg, leading to its shrinkage, a clear indication of hypertonic conditions.

B (Isotonic) YOUR ANSWER

An isotonic solution has an equal concentration of solutes inside and outside the egg, meaning that there would be no net movement of water. If the egg were placed in an isotonic solution, it would maintain its size, which contradicts the observed effect of shrinking in the provided example.

C (Hypotonic) YOUR ANSWER

In a hypotonic solution, the concentration of solutes outside the egg is lower than inside, resulting in water moving into the egg. This would cause the egg to swell or even burst, which is the opposite of what occurs when placed in a hypertonic solution.

D (None of the above) YOUR ANSWER

This choice implies that none of the provided solutions apply, but since the egg is indeed placed in a hypertonic solution, this option is incorrect. It fails to recognize the specific osmotic conditions affecting the egg in the example.

Conclusion

The egg's placement in a hypertonic solution leads to water leaving the egg, causing it to shrink. Understanding these osmotic principles is essential for predicting how cells interact with their environments, and in this case, the movement of water confirms the hypertonic nature of the solution. Thus, the egg's response is a direct result of being in a hypertonic environment.
