IB Biology - Today we heard from those students who had to cover 3.3 Meiosis and why it is so crucial to everything we know about reproduction in eukaryotes. depending on the class you were in either got a bit more information on chromosomal issues, or more in depth about meiosis, which is what tomorrow is really dedicated to. So, tomorrow you will hear from our 10.1 presenters who will take us deeper into the content, because of this I need you to do some prep.
Tonight I want you to think about the following: Imagine their were two parents with dark features (hair, skin and eyes) who gave birth to an odd set of triplets. These triplets had one identical pair of girls with blonde hair and blue eyes, and the third child was a boy with dark features, but had been diagnosed with Down Syndrome. Is this even possible? Tomorrow I want you to submit to me how this is possible (if it is). You must also explain yourself using the concepts we have learned so far. While I don't expect you to know everything at this point you should be abl eto answer this question with some really good detail.
Here's what you should know:
What is a gene? Where genes are located. What alleles are. How alleles differ. The role of mutation. And what a genome is. As to chromosomes, you should know: The differences in prokaryote and eukaryote DNA. Homologous chromosomes, karyotyping, diploid vs haploid cells, sex chromosomes vs. autosomes. As to meiosis, you should know, the process of meiosis 1 and 2, crossover and formation of gametes.
Lastly, if you run into concepts that you aren't sure if they are involved, please make include them as possibilities and I'll respond to those questions.
Honors Biology - Today we started by talking about quality in work. We looked at some examples and I hope you will all strive to do a little bit better than you did before. Next, we then wrote on the bottom of the left hand side to a "special someone" about the difference between codominance and incomplete dominance, and they wrote back to you about what they thought of your response, RUDE! :) Then we looked at the actuals from our corn crop lab to see how well our group and class numbers matched our theoretical numbers. So far, it doesn't look like it's matching, but we'll look at the all classes and see what we have. Lastly, I need you to prepare for tomorrow. ON the left hand side of your NEXT entry (yes, I know it is not titled) I want you to briefly write the difference between sex-linked and sex-influenced traits. This should only use the top left side of this entry. The right side and the bottom left should be left blank.

They want our community to thrive and they are committed to helping to improve the quality of life of those around them. Be a hero and join us as in this beautiful, family-friendly day along the bay, with music, interactive activities and more (including capes!) – all while celebrating health, and wellness.
I would love for you to participate and there are several ways to be involved…
· Participate in the 5K or Kids 1-Mile Fun Run
· Create a run/walking team
· Become an exhibitor
· Participate in the Discovery Expo
· Sign up as a virtual runner
It is collaborative efforts that help us achieve significant and lasting change in our communities, and move the dial on health and well-being. As the Live Well San Diego vision continues to gain even more momentum in advancing population health and wellness in our region, I would love for the 2018 Live Well San Diego 5K and Kids 1-mile Fun Run event to reach even more individual and families than ever before. In partnership with the San Diego Blood Bank, the County of San Diego is proud to promote an opportunity to be active along a scenic course. For more information on how you can join the movement click here. Please see attached flyer for reference.
IB Biology - Today we spent some time getting deeper into the concept of meiosis. We also spent time looking at a really gross iris transplant (not recommended). We'll continue today's presentation tomorrow, but we'll also be taking a quiz on the materials from Genes (3.1) and from Chromosomes (3.2). What you should know about these topics is listed in yesterday's blog so look above. Only brain power is allowed on this quiz. In addition to studying for the quiz, I want you to also do some review work using our strange triplet scenario. Tomorrow I want a written paper that connects the role of membrane proteins and membrane fluidity (fluid-mosaic model) to the immune response to the triplet's young immune system. How do these cellular qualities help the triplet's survive?
Honors Biology - Today we started out with comparing our theoretical results with our actual results from our corn crops. Yeah, it didn't quite get where we thought, but with more data we would have better results. next we looked at your homework from last night and also realized that most of you looked something up online, but didn't bother to understand it. I don't mind you searching online, but if you don't get it, it's useless. Lastly, we started the powerpoint on sex-linked and sex-influenced traits, our last lecture before we start a lab. We really need to finish this tomorrow so don't worry about any homework unless you want to preview the powerpoint which I have attached below.
IB Biology - Today we first took our test on genes and chromosomes (3.1 and 3.2). Next we spent time with looking at how our review topics of cell membranes connected with our triplet scenario. Tomorrow we'll finish the work n Meiosis. From here on out we'll continue to review using our triplet scenario. So tonight, on another separate written document, I want you to tell me about diffusion and osmosis as it pertains to cells of the triplets. Describe these phenomena, but also discuss/apply it in terms of dehydration and hyperhydration with our babies.
Dear John and Marco, I want my Potometers back! Bring them tomorrow please!
Honors Biology - Today we started by finishing our presentation of sex-linked and sex-influenced traits in organisms. While we've spent 3 days with lots of new learning material, we are now shifting into doing a whole lot of practice. Today you received the Blood Typing Lab which is due tomorrow. Be sure that you have glued the sheets into your notebook so that when we turn in our responses/calculations you have access to them. Tonight, just complete the lab!
IB Biology - Today we finished the detailed version of meiosis so that we have those pieces down pat! But then I asked you guys about the narrative that explains how organisms have interacted with the universe and everyone seemed equally clueless. This is not a problem that you didn't know, it just points out something we need to work on. I think it's like you sometimes can't see the "forest" because of the "trees." Do you understand this phrase? In any case it really illustrates the idea that we need to take this massive amount of knowledge and to create frameworks to hang the information on. I'll continue to use the narrative I started today, but the other framework we need to continue is how these concepts apply to our triplets. The idea is that at the end of the year you will have a global view of biology as well as a practical application of biology. So, in order to take the next step in applying concepts to our triplet situation I need you to consider the following as it applies to the developing triplets: 1) How does mitosis play a role in fetal development? 2) How could a mitotic index be used to determine rates of growth? 3) What role do cyclins play in mitosis and how do these change over a lifetime? 4) How is this process related to cancerous tumor development?
Honors Biology - Today you had an opportunity to reflect on our blood typing paper lab. You then had the opportunity to ask me questions about it. Tomorrow you will be entering your responses in a very short amount of time so make sure you know what you are talking about. Next, we started a self-assessment on ourselves to do the Create A Kid project with a partner tomorrow. Please finish this tonight. The instructions have been placed below.
IB Biology - Today we started out with the "narrative of life" to recap and connect the most fundamental ideas of why we exist. We then walked through the triplet scenarios of mitosis and hydration. While I had expected to start 3.4 today, we'll just pick this up on Monday. As to what you should do this weekend, I want you to ask yourself if you can go through the narrative that I've given you so far. On Monday you'll have an opportunity to share this on Monday. Start with the early universe and then the formation of heavy elements, then work your way up from atom, to molecule, to macromolecule, to cell, to tissue, to organ, organ systems, to organisms, etc. What fits in between? How do these connect? How to we obtain these materials? Where does the energy come from?
Honors Biology - Today you came in prepared with your blood typing lab and you did really well overall on answering the questions. Next, we matched you up with a partner to create a kid. The matching of genes happened in class, but by Monday you must produce a drawing of your child and career projection based on your combined genotypes. This should be on a separate sheet that can be displayed next to your data sheets. I've placed the instructions below.
This page contains nearly everything that you need if you missed class.
