Mon-Day 1
Bio - welcome back! We reviewed the previous information from this unit: disease, its causes, and the general forms of immunity/protection that humans have against any pathogen or toxin. We focused on the BENEFITS of having a FEVER (as long as it doesn't get too high!) to create a more hostile, enzyme-denaturing environment for the infecting pathogens. We also pointed out the benefits of inflammation in speeding up the immune response to the infected area.
We then reviewed the pathogen-specific response from helper T-cells, B (antiBody producing) cells and their memory cells, and killer T-cells.
We then discussed some diseases of the immune system:
AUTOimmune diseases such as lupus and rheumatoid fever.
We also discussed the IMMUNODEFICIENCY disease, AIDS, which is caused by HIV.
AP Chem- If you make mistakes on a unit exam, you are expected to attend extra help or to make an appointment with me sometime to clear up your misunderstanding or misapplication. Do not continue to move away from your past mistakes without learning from them; the quantity of unresolved, un-corrected yet required information is enormous and growing. Also, the best way to AVOID making mistakes on these exams is to properly prepare for them: that includes actually staying after school for extra help, coming prepared with practice questions, following test-taking advice, and perusing/re-writing the notes.
We began our unit on Equilibrium by discussing its definition, and showing the effects of equal forward and reverse rates of reaction. We then discussed the discovery of the formula for an equilibrium CONSTANT expression- which was discovered empirically after manipulating experimental data by using the coefficients from the balanced stoichiometric equation as exponents in the expression.
