Step 1: Analyze the given information and understand the concept of osmosis.
Osmosis is the net movement of solvent molecules from an area of lower solute concentration to an area of higher solute concentration, through a semi-permeable membrane. In this case, we are concerned with the SimCell membrane in the Cell-O-Scope simulator.
Step 2: Evaluate the options provided in the question.
- Pressure against the membrane: This could cause the membrane to move, but it is not directly related to osmosis. - Osmosis causing molecules to flow across the membrane: This is the definition of osmosis, so we need to investigate whether it is causing the membrane to jiggle. - The membrane not being at equilibrium: If the membrane is not at equilibrium, osmosis will occur to try to reach equilibrium. - None of the above: This would mean that none of the other options are correct, which we need to determine.
Final Answer
The SimCell membrane jiggled back and forth due to osmosis causing molecules to flow across the membrane.
