For Thursday Jan 3rd 2019: Reminder that some of the items on the homework sheet are due Thursday as well as a short test on cell structure and function: 18 MC, 2 GI, 1 short FRQ.
If you can do the following you will be good to go on the test: Describe or apply the structure and function of the following organelles: nucleus, nucleolus, ribosomes, RER, SER, Golgi, Lysosomes, vacuoles, mitochondria, chloroplasts, cytoskeleton and the three types of proteins that it is made of, types of cell junctions. Be able to discuss the importance of SA:V ratio. Compare and contrast prokaryotic and eukaryotic cells. Use your Holtzclaw Test Prep Book, it is very good. Use your online resources. What will NOT be on the test: Membranes, osmosis, diffusions, cell division. |
2018 ended with increased concern over global warming, with a significant increase in larger, stronger storms, wildfires etc. A Chinese scientist is charged with scientific misconduct in response to his claim of using Crispr technology to genetically engineer embryos that resulted in the birth of twin girls. Other Chinese scientists have cloned twin Macaques but promise not to clone humans. On the plus side, Crispr technology has been used successfully in clinical settings for therapeutic purposes. NASA reports that there is additional evidence that supports the hypothesis of microbial life on Mars in the distant past and scientists have strong evidence that terrestrial life has been on Earth for 3.2 billion years. There are clinical trials that support a 10 minute cancer test and much more. Can't wait to see what 2019 brings. Happy New Year to you and your families.
Extra Credit: See attached. Due 1.11.19 by email. Since you are sending this by email you may use Word to type right onto my form.

Your Homework Sheet is posted to the right. Read it carefully.
Reading your FRQs provided evidence that we need to discuss the use of graphed data to estimating solute concentration of tissues. See our webpage for an explanation. You have two Water Potential Quizizzes to do at join.quizizz.com You must login so that I can give you a score. · 639127 APB Water Potential DUE: Monday, Jan 14 at 11:44 pm · 159846 Water Potential and Osmosis Due: Tuesday, Jan 15th at 11:45 pm Come to class on Tuesday w/ any questions you still have. We will have a test on water potential on Thursday, Jan 17th Here is the scoop: Solute potential or osmotic potential is calculated by the formula -iCRT. The C represents the molar concentration of the tissue or cells. You get C by reading the graph: where the curve crosses the X axis the tissue is isotonic with the environment (or solution) - see the arrow. So the trick is to graph carefully and read from the graph carefully. We'll do a practice problem in class on Tuesday before we work on cell signaling. You should read the molar concentration here to be between .25 and .3 M. Plug this into -iCRT and that will give you the solute potential for the water potential equation. See the homework sheet for your work for this week. LLAP |
Water Potential Test: Tuesday 1/22/19
Your I can do this list:
1. Quizizz: APB Water Potential, 15 Q Join.quizizz.com Game Code: 741097 Due Monday, 1/21, 11:45pm 2. The test will be short and we will work w/ cell division and cell signaling. Do the Quizizz: AP Biology Mitosis Quiz to orient yourself to the steps of the cell cycle. It is important to know chromosome content, and the events that occur in interphase and mitosis. You are responsible for this information for our work on Tuesday. Your text book is excellent. Join code: 097307 Due Monday, 1/21, 11:45pm |
For Wednesday 1/30/19
We wrapped up last bell looking at the cell cycle, not in terms of the order of events but in terms of how each step or event leads to a particular outcome: producing daughter cells that have the same genetic complement as the parent cell. Something else to think about for down the road is that include external (to the DNA) markers or epigenetic markers the nurture part of nature vs nurture. The Quiz: Wednesday, beginning of bell
