Friday HBio Period 2+3 UPDATE

HEY STUDENTS!!!!!!!!

IF we have school on Fri 12-19 please still expect to take your ch 6-7 exam........I know you have all spent the last few snow days studying so you will all get GREAT GRADES!!!!!!!!!!!!

Wed HBio Period 2-3 12-17-08

In Class:
FINALLY took your chapter 6-7 exam..........after all this snow!
Collected your flow charts so I can tally the winner!
Checked off your ch. 6-7 journals........each student should have had 11 of them (do 1-10 skip 11 and do 12) for period 2 and 10 of them (1-9, skip 10 and 11 and do 12) for period 3

HW:
We are going to start a new chapter next class.....I know bad timming with X-mas break and all but you can get prepared by reading pages 160-164 of your book....who knows maybe I will have a small pop quiz to make sure you are doing all the readings I assign

D) The most common location for bound ribosomes is the cytoplasmic surface of the plasma membrane.
