Thurs-Day 2
Bio 3/6- we discussed the need for organelles in a cell to work together in order to maintain homeostasis/keep the cell alive: no single organelle can perform all of the required life functions that keep the cell alive.
We then discussed a couple of prime examples of HOW two or more organelles work together in order help maintain homeostasis. Often pairs of organelles will mutually help each other perform their functions by having one organelle make components or supply energy that is required by the other organelle and vice-versa.
Tomorrow, we will discuss levels of organization in complex organisms and also focus on the modes of transport of substances into and out of the "selective" cell membrane.
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. Check out the animation of the gas laws on Blackboard (remind me to show them in class, thanks).
The percent composition of a hydrate lab writeup is due in class tomorrow.
We still have Graham's Law of Effusion and the Van der Waal's "corrected" real gas equation to finish up this unit. The unit exam will be given next Wednesday and an after school TIMED practice will be given on Monday.
