IB Biology - Today we learned about 7 deaths in San Diego which occurred over the weekend (This is all fictional for our case study). You then asked a number of questions that were very good in trying to look for commonalities. When you left class you had symptoms, test results, and some leads to follow. Please follow those leads tonight so you can come back prepared to investigate further. YOu may also want to re-read chapter 8.1. Period 2, I will see you tomorrow to start a similar process.
Honors Biology - Today we discussed in detail how mutations work and how they affect so much of an organism. We discussed the effects on natural selection, on Chernobyl animals, on DMD patients, on growth and development, How sex cells pass on mutations, on how high energy can affect DNA, and SO much more. We now know that although some naturally occurring mutations occur, we also have high radiation, and other carcinogen to thank for these mutations as well. BUT we still haven't got to the answer about what exactly DMD patients have wrong. Before we get to that question we will expand a little bit on our knowledge of proteins but doing a lab the next time I see you. To prepare I want you to find out what the following terms mean: lactose (and what are its parts), lactase, enzymes, and substrate. A diagram would be good and you can make this on the right hand side of a new entry. Only use the top of your right hand page.
IB Biology - I finally got a chance to see all of you today. Each class broke down the mystery of the Tylenol murders, but now we need you as an expert witness to present your findings in a way that a jury of ordinary people would understand. While we know that the cause of death was from disabling cellular respiration, you also need to explain in a very simple way why the victims had high carbon monoxide levels, high lactate (lactic acid) levels, mild dehydration, cardiac tissue damage(and other tissues), mitochondrial damage, and why they had the symptoms they did. As to finding the foundation to this task, please make sure you understand 2.8 and 8.2 in your book. When I see you next, we should be able to answer more of your questions.
Honors Biology - I didn't see any of you today. See yesterday's for more info.
IB Biology - Cellular Respiration Video: https://www.youtube.com/watch?v=7J4LXs-oDCU In addition to working on your explanations, please also take a moment to Complete the DBQ on page 385. Spend a little bit of time with it, don't just slop something down.
Honors Biology - Today we worked on a lab that demonstrated some ideas about proteins. Tonight, using the data you collected, I want you to develop a CER of the "rules" about protein function on the left side of your entry from today. This should be based off of your work. Your Claim, Evidence, and Reasoning should be very clear. I have posted the combined data, lab write-up guidelines, as well as the formal lab procedures from today below. If you choose to do this as a formal write up there is a lot of extra credit possible, but know that making this a formal lab is NOT required! ....Also, if you want to redo the work you got back today, that can be redone as well. Yes, I am very generous!
IB Biology - Please look at yesterday's post to know what should be completed for tomorrow. A LOT of people wasted time today, please make sure you aren't one of them. The project is due next Friday and will be presented to freshman (the jury) when we return from break. ALSO, know that IB Exam Fees must be paid by TUESDAY when we return to school next week.
Honors Biology - I did not see you today so just look at yesterday's post to know what is due on Friday, which is a normal day.

Honors Biology - One pager on a protein of your choice. Include: 3 major pictures and captions, a border that reflects its shape, describe the function, a personal reaction, 4 color minimum, mutations of this protein, other bonus material (highlight).
