IB Biology - Today we attacked chapter 10.3 - speciation and gene pools! While we'll continue this conversation tomorrow, you also received a set of questions from a classmate. Tonight I want you to answer these questions as best you can. They will be shared in class and then returned to your classmate. If you did not receive a set of questions I want you to address the following... 1) Provide a detailed example for each type of selection: disruptive, directional, and stabilizing. 2) Describe the differences between punctuated equilibrium and gradualism. 3) Give three actual examples of different types of isolation. YES, illustrations can be VERY helpful in explaining some of this. On an additional note, Friday is the last day to sign up for AP exams. Please talk to Mr. Davis if you have questions!
Honors Biology - Today we started by reviewing questions 1-8 from the POGIL we started on Friday. I really want to make sure you are clear about your understanding of DNA. We then went through the second model and completed up to question 16 before we stopped and reviewed again. Tonight you should finish these sheets up through question 20, then at the bottom I want you to make a level 2 or level 3 question based off of the homework. Tomorrow you will get your tests back. Most of you had very strong scores, but if you didn't, make sure that something changes about how you are preparing, and that includes getting help from me!
IB Biology - Today, during 1st period, we had a great summation of the genetic concepts of gene pools and speciation, but we never got to the point of taking a quiz on the material. Tomorrow you will watch a gene pool (swimbots) simulation and be asked to apply these concepts. Be sure you understand the answers to the questions listed on Monday as well as take a moment to refresh with an overview of of the chapter. As to period 2, we did a brief review, but are a little ahead of the game. Period 2 students need to relax tonight and be ready for tomorrow. You may want to look over chapter 3.5 in preparation.
Honors Biology - Today we reviewed our work on DNA and how it replicates, and one of the important ideas that came out of today's lesson is that molecules are almost like locks and keys. Then we watched how it rolls up to be stashed in chromosomes with the addition of histones (https://www.youtube.com/watch?v=dKubyIRiN84). Next, we watched a crashcourse (https://www.youtube.com/watch?v=8kK2zwjRV0M) to review it all to us and to give us a little bit of history about how they found all of this stuff out. Now, the big idea from this second part was that scientists build up their knowledge based off of earlier scientists work. You have no homework tonight.
IB Biology - SO as of today we have covered nearly all of the material on genetics. Having all of this in mind, I want you to consider the following: Why do humans have a greater right to life? Think about this. Why does a dog have a great right to life than a fly? What is the defining factor? Have well defined reasons written on a piece of paper.
Now consider any ONE of the following quotes: The worst sin to our fellow creatures is not to hate them, but to be indifferent to them: that is the essence of inhumanity. - George Bernard Shaw
For as long as men massacre animals they will kill each other. Indeed, he who sows the seeds of murder and pain cannot reap the joy of love. - Pythagoras
Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in it's beauty. - Einstein
Which of these three resonates with you and why?
Honors Biology - Today we realized that the pieces to answering our big question of How does DNA translate into the traits we have is coming slowly. ...but it is coming. Today you had an overview of the process and I know it was a LOT of info. Remember, transcription and translation is how protein synthesis occurs. On the bottom half of the left side of the entry we started today, please write a narrative (in your own words) about the process from start to finish. Use your notes on the right side page that came from the following animation: http://sepuplhs.org/high/sgi/teachers/genetics_act16_sim.html and please bring colored pencils tomorrow.
IB Biology - Today we continued our discussion about biotechnology, GMO, and cloning. Part of my doing this really revolved around the idea that many of the things that we do are fundamentally biologically driven. Perhaps if we recognize this, it can help us make better decisions about our future. There is no homework tonight as we prepare for a virtual lab.
Honors Biology - Today we reviewed what we know so far. You are starting to see what those sentences had to say about the process of protein synthesis We covered protein synthesis and DNA basics, but tomorrow we'll find out what happens when it all goes wrong!!! If you want to watch the supplemental video I used today, here it is:
https://www.youtube.com/watch?v=5bLEDd-PSTQ Tonight for homework, make a simple 3-5 step instructions for how to use the Codon Amino Acid Table I gave you. These instructions should be written right next to the table.
IB Biology - Today we mostly discussed the ethics of being able to manipulate mother nature. One of the big ideas that we found was that most reasons for humans doing things come down to our basic instincts like I mentioned yesterday, but today there was an interesting idea that arose. This new idea was the difference between harvesting animals and plants for food. We really struggled with finding the real dividing point between respect for life and how plants and animals are different. Regardless, I want you to realize that although we have more work to do, this unit is primarily over. In order to get you to prepare for the upcoming unit exam that you'll take I need you to review these chapters on bioninja and to come prepared to ask questions. This means you should prepare questions on your muddiest points. You could waste your time by asking simple questions, but why? Help your self and ask meaningful questions. I expect you to have a minimum of 5. The bioninja pagesa are posted below:
Honors Biology - Today we reviewed the homework which was how to read the codon amino acid table. Next we reviewed the function of replication and protein synthesis, and lastly took some new notes on DNA that included Mutations. The two major types are called point mutations and frame shifts. The point mutations were non-sense, mis-sense, and silent types, and the frame shift mutations were simply insertions and deletions. Your homework tonight was, using the sentence "MAT AND SAM EAT CAT,"(or whatever sentence your class came up with) was to modify the sentence to show each of the types of mutations. When you are done, be sure to box these sentences with the same color coding you used on your right hand side.
This page contains nearly everything that you need if you missed class.
