To answer the question effectively, let's analyze the provided table and the context of osmosis.

Understanding the Context:

Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration. In this experiment, dialysis eggs are placed in different solutions to observe changes in their mass over time due to osmosis.

Table Analysis:

The table shows the changes in mass of four dialysis eggs placed in different solutions (water, 1% sucrose solution, 10% sucrose solution, and 30% sucrose solution) at various time points. The initial mass of each egg is recorded at 0 minutes, and subsequent changes in mass are noted at 15-minute intervals up to 75 minutes.

Key Points:
  1. Egg 1 (placed in water): Since water is a hypotonic solution (lower solute concentration compared to the egg's interior), water will move into the egg, increasing its mass.
  2. Egg 2 (placed in 1% sucrose solution): This solution is slightly hypertonic or isotonic compared to the egg's interior. The change in mass will be minimal or slightly negative.
  3. Egg 3 (placed in 10% sucrose solution): This solution is hypertonic, so water will move out of the egg, decreasing its mass.
  4. Egg 4 (placed in 30% sucrose solution): This solution is highly hypertonic, so a significant amount of water will move out of the egg, leading to a substantial decrease in mass.
Answering the Question:

The table is incomplete, but we can infer the expected changes in mass based on the principles of osmosis.

Expected Changes in Mass:
  • Egg 1 (water): Increase in mass over time.
  • Egg 2 (1% sucrose solution): Slight increase or minimal change in mass.
  • Egg 3 (10% sucrose solution): Decrease in mass over time.
  • Egg 4 (30% sucrose solution): Significant decrease in mass over time.
Summary:

The table provided is designed to track the changes in mass of dialysis eggs placed in different solutions over time due to osmosis. Based on the principles of osmosis, we can predict that Egg 1 will gain mass, Egg 2 will have minimal change, Egg 3 will lose mass, and Egg 4 will lose a significant amount of mass.
