Thurs-Day 1
Bio - we did two pedigree charts in detail, from the youngest descendants to the oldest ancestors, showing how to predict possible genotypes from the observed phenotypes. We also saw how to spot whether a trait is caused by a SEX-LINKED ALLELE (ON the X chromosome) or by an autosomal (non-sex) allele.
We then discussed both point/single genetic mutations as well as the types of LARGE-SCALE chromosomal mutations caused by nondisjunction, duplication, translocation, deletion, and inversion.
We worked on our Human Inheritance labs.
AP Chem - we completed a Ksp precipitation problem in which we predicted the formation of precipitate by comparing Ksp toQsp; we determined the percent precipitation, and then we determined the number of grams of precipitate that formed.
Tomorrow, we have a challenging test on buffers, titrations, and some Ksp up to molar solubility in a solution with a common ion (i.e. NOT the material from today or the second period on Wednesday) .
Do as many problems as possible; the test will be a mix of problems from the notes and two practice tests.
