Mon-Day 1
Bio - we discussed the structures and functions of the male reproductive system and show how each feature is an ADAPTATION=ADVANTAGEOUS CHARACTERISTIC for sexual reproduction i.e. increasing the likelihood that a sperm cell will reach and unite with an egg cell.
We also began the same analysis of the female reproductive system and then we labelled a worksheet of the male and female reproductive systems.
AP Chem - we explained the relative strengths of OXOacids by focusing on the CENTRAL ATOM adjacent to the O-H bond OR the number of O's attached to the central atom that is adjacent to the O-H bond. As usual, these structures affect BOND POLARITY which affects acid strength; however, the O-H BOND STRENGTH is nearly identical for all O-H single bonds, therefore the bond strength factor is insignificant in determining relative acid strengths.
