AP Chem - we began our final unit of the course: Electrochemistry. We discussed the energy advantage of electrochemical cells, the construction of the cells, the redox reactions that occur via a conducting wire and salt bridge, the meaning of voltage/potential difference, and the conventions used in writing out Voltaic/Galvanic cells.

Bio - we discussed the various types of gene and chromosome mutations. We noted that gene mutations are just changes of ONE NUCLEOTIDE in the base sequence: addition and deletion point mutations are FRAMESHIFT mutations, whereas a substitution mutation is not.
Chromosomal alterations are either parts of an entire chromosome containing many genes are added, deleted, or transferred to or from a chromosome, or a change in the number of chromosomes in the nucleus of a cell
