with the multiple choice question with pasteur's experiment, what did everybody put?


It was the one that related to why there was scum in the second one. I didn't know if the lines were a lid... so I said the beaker wasn't boiled. What did everybody else put?

Yeah it was a horrible diagram... but I assumed it was a lid since they said they were modelling his experiment and it had said nothing about boiling in the writing so I said they hadn't.

That feel when you walk out of the exam and your answers don't include some of things everyone else included.
Made some sillies with mc estimating 16/20
Short answers didn't go quite well as I wanted to as I forgot to mention things in some of my answer.
Communication was fairly easier just happened to not talk about action potential in a ii) other than that hoping for 80 raw [emoji24]

osmosis involves water and some solutes so pretty much 2 concentrations of particles. diagram only shows 1 conc of particles going from high conc to lower conc... think of diffusion of gases in a room i guess
