Da Scribe of Da Day!

So we started off today by getting our tests back and then went into some notes on INFECTIOUS DISEASES VS. REGULAR DISEASES. We also started the beginning of our new unit on diseases and learned about deadly pathogens that get inside our immune system and harm us, and also viruses. We were also introduced to the Disease of the Day in where we will be investigating a disease for homework every day, or usually every day. We then found out Ms. Stein is GOING TO HAVE A BABY! Congratulations Ms. Stein! We ended with a short video that we will continue next class that had to do with a doctor named Semmelweis that had to convince his other fellows to wash their hands!               NEXT SCRIBE IS Shaaaaaaaaaaaaaaaaaaaaaaaaaannnneeeeeeee.

Anyone on this site hiiiii its tessa. ok so i don't really understand the cell cycle... what does each cell look like? that big bird stamp sheet totally confused me haha, I made BenS do all the work. i've trieed so hard to memorize them but it just doesn't stickk... ANY ADVICE?

My Dirty Point Of Muddiness.

My muddiest point is about enzymes. Like I know that they are catalysts with protein that speed up chemical reactions but can someone further explain this or like exactly what catalysts are?

Here's what went down today!

Here's what went down today in Mrs. Stein's 8th period bio class! We took notes on 10.3 which was all about regulating cell cycles. We learned that cyclins were the proteins that regulated the cycle. During interphase, they signal spindle information. How exciting! 2 types of regulators are INTERNAL REGULATORS and EXTERNAL REGULATORS. Internal regulators check the cell and make sure the cell is ready for mitosis. It's giving it approval, like the "Go ahead!" External regulators speed and slow down cell division.

We learned that the causes of cancer are:

*Carcinogens (cancer-causing chemicals)

*Mutants ( DNA overproduce growth factors)

*Some viruses (they mess with your DNA)

After we took these fantastic notes, we got in our lab groups and make sure our big bird stamp sheets were finished. Then the bell rang!

Muddiest Point

Ok, I understand most of the things from this chapter, except for the stuff about ATP and ADP... I don't know what the difference is!

I know that they are sourced of Energy, but that's it! So can someone please tell me what they do?

MUDDY BUDDY

My muddiest point is about the chromosomes. Im kind of cunfussed about all the differnt things they do, especially during mitosis when all the confusing names come along (chromotin, chromatid, they all sound the same!)

Hey point get out of the mud!!

Hey its Jarod. My muddiest point would have to be the difference between chromatin and chromatid. they both sound the same and look the same. help me.

Cell Cycle

Hey guys, it's Eunice Lee :D


Today in class we searched for phases of Interphase and Mitosis in an onion cell. We also counted how many cells were in different phases!

In Interphase there is the G1, S, and G2 phase.
In G1, the cell does most of it's growing.
In S-phase, the DNA is replicated and there is twice as much DNA.
In G2, organelles are produced and the cell prepares for the M phase, or Mitosis.

In Mitosis there is Prophase, Metaphase, Anaphase, and Telophase.
Prophase is the longest phase, the nucleus condenses and the chromosomes can be seen. Then, the spindle starts forming.
Metaphase is the shortest phase, the chromosomes gather in the center of the cell and line up. The middle of the chromosome is the centromere which are connected to spindle fibers.
Anaphase, the chromosomes are separated and move to the ends of the cell by the spindle fibers.
Telophase, the chromosomes spread out and the nucleolus starts to form in the cell.

Also remember to post your Muddiest Point by MIDNIGHT!
And Comment on a post before MONDAY BY MIDNIGHT!

Have fun at Homecoming :)

Next Scribe is Kara

Metaphase, Anaphase and confusion. O MY!

What is the metaphase and anaphase? arnt they kind of the same thing?

My Muddiest Point

My Muddiest Point in the cells unit was that I did not know the difference between the nucleus and the nucleolus and where they are located. If anyone could help that'd be great!

Muddiest Point

Hi, Eunice Lee here.
I think my muddiest point is Osmosis. I don't understand it completely, any help? :(
