CELLS GROWI, AGE, DIE..
Today in class we discussed the truth that all cells live and then eventually they die. For an organism to sustain health and vitality it must regenerate new cells to replace the old, damaged and worn out cells.
We looked at many different cells. Skin cells, blood cells, brain cells, even stomach cells. Each have their own unique responsibilities to the organism and some of the last for years like brain tissue, some only day such as stomach cells.
We discussed the issues of how cancer develops and what factors can lead to it.
Tomorrow in class we will cover indepth the topic of cancer, some text questions and sorts.

In the text book on page 28 question #5 says "from youy knowledge of cancer and cell division, propose a model to explain how sunscreen works. How could you determine whether you model is accurate." do you just want us to say how sunscreen works or do you want us to build a model?

The question in terms of build a model simply asks you to develop a thinking solution or theory on how sinscreen works, and you must also answer the first part of the questions as well. Remember not all models have to be built but can be illustrated, use formulas, etc.
