Today in class Mr. Park started off with ending his powerpoint about diffusion because he wasn't there the day of that lab. What he wanted to talk about was osmosis- which is the diffusion of water through a semi-permeable membrane. Look at the diagram below to see an example of it.
After Mr. Paek finished going over Osmosis he moved on to the last part of the unit, which is cancer (it will be included in the test). These following bullet points is what he went over in his powerpoint and discussion.
- Cancer- is the uncontrolled growth of cells
- it caused by changes in a cell's DNA, which can lead to a unrestrained cell reproduction
- It makes cells produce a growth factor and never stops dividing OR don't produce a suppressor protein and it never stops diving.
The last part of the notes was about the two types of tumors. The two are benign and Malignant.
- Benign- is a slow growing, noninvasive cell which is also not metastasis. (not cancerous)
- Malignant- is a rapid growth in cells that is invasive and metastasis ( can jump to other parts of the body) it is cancerous.
A couple reminders: 1. We are meeting in the Lyceum tomorrow for a bio day
2. We have a test on Wednesday about the cells, their functions, cell cycle and cancer
3. The homework was to do the unit 2 review packet for wednesday and optional for extra credit is the objectives sheet.
4. Last is don't forget the cancer research paper is due next week so keep researching and working on it
