Final Exam Grades

2009-06-10T14:12:00.000-07:00

What you see on faweb right now is your total number of questions answered correctly out of 164.

I will not know the curve until Friday morning after period three takes the test.

At that point I will adjust the curve and add the 5% points to the students who tood the final exam!

See me with questions!

finalized room and times for essay make up

2009-06-09T10:44:00.000-07:00

If you are interested in taking the essay to add some points to your ch 16-17 exam, here are the two options.

You will only be given one half hour to compete the two essays.

Thursday: Room 102 with Ms. Jager from 12-12:30

Friday: Room 123 with Mrs. Jenkins from 9:45-10:15

Opportunity to add 10 points to your ch 16-17 exam!!!

2009-06-08T17:46:00.000-07:00

Dear Honors biology classes:

As many of you know, I had some very respectful and mature students come after school today and talk to me about the last exam. It is because of them, and how wonderfully they handled themselves that I am offering this opportunity. My hope in doing this is that it indirectly encourages all of you to advocate for what you believe in during your future endeavors in an equally mature and respectful manner.
You will each have the opportunity to earn 10 points (not to exceed 100%) onto your chapter 16-17 exam score by answering 2 essay questions. One will be on DNA replication, the other Gene expression.

This opportunity will be offered on two different dates; hopefully one of them will be convenient for you.

The first date is Thursday 6/11. It will take place after school during the make-up exam. I will post a room number tomorrow once I find the location/time of the make-up exams.

The second date will be on Friday 6/13 and will happen RIGHT after the last final in room 123.

Please be advised these essays will be graded on the facts you can provide to ensure me you have mastered the material that is often deemed, “the central dogma” to biology!

See me, or email me if you have any questions.

Good luck on your finals!

A lot of important info

Final version of debate papers due 6/8...that is an "A" day so don't leave yours at home

I will be checking your final exam review journals on this day as well...

Final:
Bring the following to the final exam:
pencil
textbook
water

The final has a lot of questions on it. Students will only be given one and a half hours to complete. You can come early to get your book checked in so we can start right at the starting bell. Please work on your study guides as this will enable you to answer the questions faster and hence earn more points. The final's curve will be out of whoever answers the most questions correctly.

Ch 14-15 Exam Next Class

Journals due next class, just a reminder I am only collecting journals that are labeled as "journal 1," "Journals 2, " etc. See prior posting for any journals you may have missed!

NEW JOURNAL…..NEW RULES!!!!!!!!!!
For FULL credit journals MUST be labeled by journal entry!

Journal 1 Chap 14/15
Read page 252 and provide some “facts” about who Mendel was!

Journal 2 Chap 14/15
1) Cross a homozygous dominant tall plant with a heterozygous tall plant and anaylyze the genotypical outcomes of the F1 generation…phenotypical….
2) Which of the following are genotypes and which are gametes?
a. AA
b. A
c. Bb
d. BB
e. C

Journal 3 Chap 14/15
1. BbDD (B brown, D deaf) is mated to one with BBdd. What is the chance of obtaining an offspring that is
a. Brown/NOT deaf?
b. Brown/deaf?
2. When you are done with this journal finish your ws from last class…we are going to have an overhead of notes in just a sec!

Journal 4 Chap 14/15
Do overhead practice problem set 11.5

Journal 5 Chapter 14/15
Considering incomplete dominance and the following key answer the following question.
TA = tall
TB = short
PR = purple
PQ = white

Parents = TATBPRPQ x TATAPRPR

1. What are the chances of having a medium/lilac flower?

Journal 6 Chapter 14/15
gene
allele
principle of segregation
principle of independent assortment

different forms of a gene for the same trait

The law that states the different forms of two alleles (homologous chromosomes) will separate independently of each other into different gametes

a segment/piece of DNA that codes for a trait

This law states that factors for different characters (on different chromosomes) separate independently of each other. This is why you have to consider EVERY possible combination that can occur when you are tracking a dihybrid cross

Journal 7 Chapter 14/15
1. Using pages 265-268 make a list of all the autosomal dominant and a list of the autosomal recessive inherited disorders and provide a brief explanation of each.
2. Note to self, please be sure to read and understand pages section 15.4 of your book. We may not be going over this in class but it will be on the test! Show PPT on this from notes!
3. Today Jenkins will show you some examples of sex chromos altered

Journal 8 Chapter 14/15

Make sure your journals are in order for next class when they will be checked off

Make sure to pay attention to chromosomal # abnormalities and autosomal dom/rec and sex linked diseases info..see blog for full description

1. Explain why generally, it is not possible to determine whether nondisjunction failed to occur in oogenesis or spermatogenesis. However, it is possible to assert that xyy resulted in nondisjunction in spermatogenesis

Decide whether the following statements apply to amniocentesis “A” or chorionic Villa Sampling “B”

2. Obtains cells from the region where the placenta will develop
3. Takes a sample from the amniotic fluid from the uterus
4. Can determine more types of abnormalities. In other words, is not limited to just a disorders revealed by a karyotype
5. Of the two procedures, this test has the lowest risk of a spontaneous abortion
6. This test can be done earlier in the pregnancy

7. Decide the inheritance pattern of the following pedigrees….be ready to explain!

Journal 9 ch 14-15
Mom: Dad
homozygous hemophilia Has hemophilia
homozygous cystic fibrosis carrier of cystic fibrosis
blood type AB Homozygous for blood B
Rh- Heterozygous Rh+
Heterozygous for Huntington’s Disease Heterozygous for Huntington’s

Showing your work mathematically, please give me the phenotypical fraction among all the offspring

Time to work with your assigned group on the cancer reading
presentations are due next class
I suggest each student print out a copy of the cancer reading questions that are fair game for the test and bring them to class with you so you can answer them while presentations are going on
see blog for presentaions details
don't forget you will be turning in your vocab words and grading sheets for your group members along with a hard copy of your project

cancer reading questions

2009-03-04T11:06:00.001-08:00

Print out and bring to class

Cancer Reading Questions

Please answer the following questions on a separate piece of paper. These questions are fair game for the test.
Please DO NOT WRITE on the cancer reading, it is just a reading to get done in class.
Feel free to talk this information over with your peers!

Questions:
How are bacterial infections and cancer infections different?
Damage Control: Tumor Suppressor Genes
What four things do normal cells have in place as a way of damage control?
What is cellular suicide called?
How is necrotic cell death different from apoptosis?
P53 is a key protein involved in detecting cellular damage, what are three of its major functions?
What happens when the gene coding for p53 is mutated?
What is the definition of a tumor suppressor gene? What are some of the jobs these genes encode proteins to do?
Why is a mutation in a tumor suppressor gene bad?
Promoting Cellular Division: oncogenes
What happens when protoncogenes become oncogenes? Give a few examples
What would happen to a cell that had an oncogene mutation and a tumor suppressor mutation?

11 What are the six hallmarks of cancer cells? Please briefly explain each!

a.
b.
c.
d.
e.
f

Evolution of Tumors:
What are some of the many changes that have to occur in the cell for it to become cancerous?
How is cancer linked to evolution?

cancer proj reqs

2009-03-04T11:05:00.000-08:00

Cancer Jig-Sawing Presentation Rubric
Five Groups Total for each class!
1) Cancer cells have profound genetic defects-STOP at cell cycle title
2) Cell Cycle – stop at six hallmarks of cancer title
3) Six hallmarks of cancer 1-3
4) Six hallmarks of cancer 4-6
5) Evolution of tumor cells – end of packet
Below you will find the criteria for your presentation. You will be given one class period to organize your thoughts and take notes on your topic and talk with your group members. Please note, the reading packets will not be available outside of class. You are invited to stay after school/Reps if you need more time with the packet.
1) Equal participation by all members in the delivery of your topic
2) Good flow of information…presented in order it was given in the reading
3) Short, to the point notes. Remember your notes should prompt you on what you are presenting about. You should glance at them every once in a while to keep your focus while you are in front of the class or to remember big words but you should in NO WAY SHAPE OR FORM READ NOTES to the class. You really should have your material memorized when you get up to present!
4) Wordy notes will not be acceptable! Your notes can either be PPT or overhead style or BOTH like I often do. Use the PPT for images and overhead for notes!
5) An overall feeling by Mrs. Jenkins that your group has a thorough understanding of what you are presenting about
6) The ability to answer any questions your peers may have to re-clarify what you presented on! Believe me, there are a lot of unanswered questions out there about cancer and I don’t expect you to know the answers!
Notes:
1) This will count as a lab grade
2) You will receive an individual grade and a group grade
3) If anyone in your group is not prepared it will reflect on the whole “group” grade
4) Make sure any computer portions of your project work before the presentation day or your grade will be affected!
Turn into Mrs. Jenkins:
1) Any part of your presentation. If you do a PPT, please print them out and give me a HARD copy. Also please plan to turn in any overheads or other notes to me. HARD COPIES only!
2) A piece of paper with all the group members listed, including your own name. Please list your name as the first name. On that sheet of paper, please give each member a grade based on how much effort they put into their part of the project. Use the grading scale and example below:
Jenny Jenkins 3
Denise Farrell 3
Dawn Guildner 3
Katie Cave 3

1 did not collaborate well with group, was unprepared, had not idea what they were talking about, read their slides etc.
2 provided an average amount of effort, did not fully understand their material, mostly prepared but had to read a good amount of their slides
3 really worked hard, was prepared, helpful in the group understanding the material got up and rocked the presentation portion of the project

I am not available after school on Monday as I have an academic council meeting and I will be out of the building at a conference all day thurday and Friday!

Remember it is part of the CCHS handbook guidelines that if you are absent on the day of a test you have one school day to make that up. Please see me if you have concerns. For anyone who can not stay this day and has to take the test the following week, your exam will be all essay.

Have a great weekend!

Journal 7 HBio Chapter 6+7

1) What kinds of fats would you expect a cell membrane to be composed of if it was found in a plant cell living in a cold environment? Explain your answer
2) How did scientist “prove” that proteins were span the entire length of the cell membrane….what is this called…..hint a buzz word found on page 124.

Journal 8 HBio Chapter 6+7
1) What is the major difference between channel and carrier proteins…how are the alike?
2) What are the three tonicities a plant cell can have. What direction would you expect waterflow in a cell that is hypertonic?
3) Is facilitated diffusion active or passive transport? How come we call it “facilitated” diffusion? How are/aren’t carrier and channel proteins active in this process?

Chapter 7 Journal 9
1) Explain how the presence of cholesterol affects the fluidity and freezing point of the cell membrane
2) Using figure 7.13 explain why a “normal” conditions for an animal cell are “flaccid” conditions for a plant cell…..hint think of the cell wall plant cells have! In addition compare and contrast lysed and turgid. Normal and flaccid. Shriveled and plasmolyzed.
3) Considering only the movement of water AKA osmosis………….what would happen to plant cell that was placed in a hypertonic solution. WHY?

Journal 10 chapter 7
1) Nerve cells establish a voltage across their cells with the help of the sodium-potassium pump. Does this pump use or generate ATP, why?
2) How come the sodium potassium pump is not considered a co-transport molecule if it is transporting two types of solutes and the hydrogen pump is?
3) If a small water serpent that allows water to flow through its cell membrane with the help of aquaporins was to swim from a hypotonic environment to an isotonic environment would you expect the activity of its contractile vacuole to increase or decrease? Why?

Journal 11 Chapter 6+7

E) They serve only a structural role in membranes.

2) Which of the following statements is correct about diffusion?
A) It moves water from high to low concentrations.
B) It requires an expenditure of energy by the cell.
C) It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.
D) It is an active process in which molecules move from a region of lower concentration to one of higher concentration.
E) It always requires integral proteins in the cell membrane.

Use the diagram of the U-tube in Figure 7.2 to answer the questions that follow.

The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucrose. Side A is half filled with a solution of 2 M sucrose and 1 M glucose. Side B is half filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels on both sides are equal.

Figure 7.2

Journal 12 Ch 6-7
Using page 137-138 of your text, explain the following:
1) What is the difference between endocytosis and exocytosis?
2) How do both of these processes differ from just normal diffusion and osmosis? Hint: think of BULK!!!
