I wrote that the sugar molecules diffused from the high concentration (outside the egg) to the low concentration (inside the egg) which is why it gained mass. The question didn't state if it was in a solution of water or not so I was hesitant to state that it was osmosis. I think I got it wrong anyway...
What did everyone put for the question with the bell jar model of the human ventilation system? I was really stuck on why the 'diaphragm' flattening caused the balloons to inflate, I feel like I should know this but I was stumped!
