Fri-Day 1
Bio- Outline text Ch. 36-3 is due on Monday. This weekend, I will post answers to the class worksheets from last week; I'll also post some review/summary notes and a PowerPoint.
We discussed the difference between physical addiction and psychological addiction: withdrawal from physical addiction makes a person physically ill whereas withdrawal from psychological addiction does not make a person physically ill. We noted that the psychological "feeling" that a person needs a particular drug is caused by electrochemical impulses between neurons (which cause ALL feelings).
We discussed drug tolerance, which can be caused by the saturation of the neuron receptors BY the frequently used drug. We also talked about withdrawal from and treatment for addiction.
We then began some review for Tuesday's exam on the nervous system and we discussed the reflex arc lab.
Chem 7- we did some more gas density at STP to molar mass (and vice-versa) problems. We then began our review for Tuesday's exam by doing a percent water in a hydrate problem from raw lab data. This weekend, I will post answers to most of the worksheets and review packet problems.
Chem 8/9- we did some more gas density at STP to molar mass (and vice-versa) problems.
We then discussed the "percent water in a hydrate lab", which we will finish on Tuesday. This weekend, I will post answers to most of the worksheets and review packet problems.
