Fri-Day 1
AP Chem - We had a detailed discussion of what CAUSES pressure in a container of a sample of gas. By focusing on the 1. pressure causing collision frequency of the gas particles with the container wall and 2. the pressure causing kinetic energy/force of the collisions, we can explain/reason any of the gas laws.
We went through each of the gas laws, which are merely subsets of the ideal gas law by holding two variables constant, and seeing how/why the other two variables relate to each other via the above two factors.
Bio - we took the unit exam on Cells and Cell Transport.
Of course, practicing the various explanations of osmosis through cell membranes in hypertonic and hypotonic solutions was a big help in prepping for this exam, as was writing out the explanations of using indicators to detect the diffusion or lack thereof of glucose and starch, respectively.
Our three examples of cell organelles working together provided excellent prep for the homeostasis question.
