Answer:

The purpose of the experiment was to investigate the effects of different solutions on the integrity of the plasma membrane. In the part of the experiment with the eggs, the independent variable was the type of solution used (water, vinegar, corn syrup), while the dependent variable was the appearance and texture of the egg membrane, and the control variable was the initial state of each egg.

The hypothesis based on observations and scientific principles could be that the plasma membrane is selectively permeable, allowing certain molecules to pass through while blocking others. This hypothesis can be tested by conducting experiments to observe the behavior of different molecules when they come into contact with the plasma membrane.

We used a combination of microscopy techniques, such as fluorescence microscopy and electron microscopy, to visualize the plasma membrane and its components. Additionally, we performed biochemical assays to measure the activity of specific membrane proteins.

To experiment with and learn about the plasma membrane, we used a fluorescent dye to visualize its structure and behavior. The procedure involved labeling cells with the dye, observing them under a microscope, and analyzing the results to draw conclusions about the membrane's properties.
