Tues-Day 2
AP Chem - we finished up the lengthy IMFA exam, and then we focused on the cause of vapor pressure.
We looked at the reason for vapor pressure depression when a solute interacts with a solvent.
We explained Raoult's Law, which holds for ideal solutions.
Bio - we gave another example of endocrine gland hormonal regulation of blood glucose - in this case, low blood glucose, caused by fasting or consuming insufficient carbohydrates, can be corrected via the action of the pancreatic hormone, glucagon. We went through the entire mechanism, emphasizing the negative feedback component that once normal blood glucose level is restored, the glucagon gene in the pancreas alpha cells is turned OFF, thus glucagon secretion STOPS.
