Question

cell transport
use the following passage and illustration to answer the question.
an osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. the mass of each egg was measured to determine how much water diffused into or out of the eggs. the eggs were first soaked in vinegar to dissolve the shell. each egg was then placed in one of three different solutions for 24 hours. the table below shows the results of the investigation.
osmosis in cells
what prediction can be made if the eggs were placed in a solution with 50% water and 50% solutes? (3pts)
a the eggs would gain mass.
b the eggs would maintain the same mass.
c the eggs would dissolve completely.
d the effs would lose mass.

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In the corn syrup (5% water, 95% solutes), the eggs lost mass (negative percent change). In distilled water (100% water, 0% solutes), the eggs gained mass (positive percent change). A solution with 50% water and 50% solutes has a higher solute concentration than the egg's internal environment (assuming the egg has a relatively low solute concentration compared to 50% solutes). So, water will move out of the egg (from lower solute concentration inside the egg to higher solute concentration in the solution), causing the egg to lose mass.

Answer:

D. The eggs would lose mass.
