Thurs-Day 2
Bio 3/6 - we discussed common disorders of the endocrine system: hyperthyroidism and hypothyroidism/goiter, diabetes, gigantism, and dwarfism.
We then went through a step-by-step detailed explanation of the regulation of blood glucose via negative feedback involving the hypothalamus and the pancreas.
AP Chem - we did another descriptive chem problem set and then we discussed intermolecular forces of attraction. The degree and type of attraction depends on
1. the "polarizability" of the molecule i.e. the number of electrons in the molecule that can be randomly shifted to one "side" of the molecule or another.
2. the degree of a permanent dipole (if any) that exists in the molecule, which is based on the degree of ASYMMETRIC distribution of electrons, which is based on molecular geometry and electronegativity differences between the bonded atoms.
