Hey guys, sorry for the late post...anyways, here's what we did in class yesterday (as today was a BIO DAY!!! I mean c'mon how interesting was that? "I had a little birdy, his name was Enza, I opened up the door and influenza"...haha so weird!!!!))
First we started off by turning in our multi-flow map and since Mrs. Stein's computer was down, we skipped the star&wish for Michael B's blog. Make sure to check out his blog and to comment on it.

Then when began to take notes in class, and I titled mine "Cancer Notes"
Here's how they looked:
Plant cells:
-Cell plate forms between cells.
-No centrioles.
-Spindle fibers
-Stages of Mitosis (PMAT)*
Animal cells:
-Centrioles
-Cell pinches at cleavage furrow.
(SAME AS PLANT CELLS):
-Spindle fibers
-Stages of Mitosis (PMAT)*
*Note: PMAT stands for the four stages of Mitosis; prophase, metaphase, anaphase, and telophase.

Then we went on to try to understand PH, which can be found in your text book on page 43-44.
Notes involving PH:
Acid is at a PH level at 14, a neutral is at a PH level 7, and a base is at a PH level of 14.
Examples: acid: stomach acid, soda; neutral: pure water; base: soap.
-If more positive charges than negatives, then it's classified as an acid.
-If it has more negative charges, then it's classified as a base.

We moved onto another section of notes: regulating the cell cycle, which is what our previous HW assignment was on; here are some notes:
-Cyclins are proteins that regulate the cell cycle.
-Spindle formation is during Interphase.
Ask yourself this question: What does DNA control?
And answer with this (one): DNA contains the instructions for making important proteins.
Note: If this goes wrong or bad, then the cell can either: 1) divide out of control or 2) not divide at all.
-The cell has internal regulators that check and make sure the cell is ready to go through Mitosis. (Spindle fibers, replicated DNA, etc.)
-External regulators, on the other hand, are out signals meant to help speed up OR slow down cell divison. P53 is an external regulator.
(Note: such as wound healing or contact inhibition.)
-Caginogens are things that cause cancer, such as the follow:
~tobacco
~UV rays

That was all for the notes we jotted down in class on Monday, here's the homework:

That's all! The next scribe is Jordan.

Good luck studying, everyone!
