Biology 2nd 6 Weeks Exam 2024-2025

During an experiment, a student places a raw egg (inside the shell) into a vinegar solution. After the vinegar dissolves the eggshell, the student places the egg into a beaker filled with water. Predict what will happen to the egg next. Select TWO correct answers.

• The egg will shrink in size due to diffusion of water.

• The egg will swell to a larger size due to osmosis.

• ATP will be used for energy to shrink the egg in size.

• Passive transport will allow water to enter the egg to balance the concentration of water inside and outside the egg.

• The egg will swell to a larger size due to active transport.
