January 8/08

**Reminder!! Field test on Friday January 9**

What did we do today??:

1. We marked the Nervous System worksheet from Monday and then we talked about the long answer because it ended up not being included for marks.
2. Then we marked the Endocrine system worksheet, also from Monday
3. Next we did a "memory dust off" as Mr.C called it, tried to remember unit 2, the reproductive system. While we remembered we were also going through what we need to know

• Some of these things included:
• Hormones, Which hormones control what?
• Technologies (examples of these can be found in the study guide)
• Mitosis/mieosis
• Spermatagenisis/ oogenesis
• Menstration (Be able to put it on a 'calendar' (days = whats happening) and know what hormones are involved.
• Be able to understand how contraceptives work

1. Then we again went into the study guide from AB learning and went through the unit on reproduction, including the diagrams. ( Mr.C told us to be able to think 3D when it comes to diagrams because there is a chance we will get a side view of the internal organs)
2. After all that is when the questions came! 2 multiple choice sheets due Wend. January 9
3. We were also to do the questions in the study guide and Mr.C recommened that we pick 5 words that we are unsure of in the glossary and define them.
4. Mr.C also wrote a list of Useful Diagrams from our textbook on the board this list was:

• 1. Pg 411-- 17.5, pg 417--17.9
• 2. pg 414 --17.7
• 3. pg. 416--17.8
• 4. Pictures and graphs/case study pgs 419-420
• 5 pg.424--17.5
• 6. pg. 425--17.6

Thoughts:

With some many birth control technologies for men including such things as vasectomys, why is it that most men expect women to be the ones to have their tubes tide?? heck we're the ones to give birth, guys should just be greatful that they don't have to do it and be a doll and be the one to have their tubes tied. Men should have to go through some pain for kids too! (come on guys! give us a break, through most of history us women have been the ones at home being the home makers, looking after the kids and such not top mention we're the ones that have to go through all the pain of labour). We've done so much for you over the centuries, now it's your turn to do something for us. Be kind, get tied!

Additonal insight:

So Iwas curious, what is the actual rate for vasectomy's considering every guy I have ever talked to about vasectomy's (and that's quite a few) have said that there was no way that they would ever do that and that it's the women's responsibility to have their tubes tied, not the men. I found this website kind of interesting, esspecially the parts pasted below:

http://www.mamashealth.com/men/vas.asp

Vasectomy Statistics
Approximately half a million vasectomies are performed in the United States each year.
About one out of six men over age 35 has been vasectomized, the prevalence increasing along with education and income. (ok so the half a million that are preformed is almost impressive, but what's this one out of 6 stuff? come on now!)

Masculinity and Sexuality
Vasectomy does not affect production or release of testosterone, the male hormone responsible for a man's sex drive, beard, deep voice, and other masculine traits. The operation also has no effect on sexuality. Erections, climaxes, and the amount of ejaculate remain the same. (Now won't you look at that! you manly men don't have to worry about loosing all of your maleness! Women will still like you! )

A day of double bio!!! yay!

What did we do?:

REVIEW, REVIEW and some more, REVIEW!!!
Block one:

• Welcome back from xmas break.... joy
• We found out that we have a bio field test (multiple choice) on friday, January 11 and a written response test sometime next week.
• **Mr. C says that if we do well on this test (the MC) we can use that mark to replace any unit exam mark.**
• Found out that we will be getting a MC 'quiz' at the begining of every class (will have to hand in two of them for marks )
• Got a booklet that has all the learning objectives in it, so that now we don't have to go rumaging through our binders looking for all of them. ( That's a positive thing for all of us who have no idea even where to start to look for those objectives in the mess of papers we call our binders.)
• We got a study guide from Alberta Learning, we went through this in both classes. This book also has a list of study tips that we went over.
• Unit one review took up the rest of the class, in the morning we reviewed the Nervous system and got a worksheet to fill out, this is due January 8. This worksheet also included stuff from the ear and eye sections of this unit.
• **Key point with the ear and eye stuff, we need to know how these are connected to the nervous system.**

Block Two:

This class was a little more laid back.

• We reviewed the endocrine system!
• We got, yet another, multiple choice worksheet to fill out on the Endocrine system, this is due January 8th
• Mr. C also assigned us to choose five words from the Nervous system and 5 from the endocrine system that we are unsure about and to find a deffinition for them, also due on the 8th of January. (There is a glossary of terms that we need to know for the unit in the Alberta learning study guide)
• This class we also got to see our marks from the last unit exam and where our average stood.
• ** For the endocrine system REVIEW MR.BLANKEY and the endocrine chart we filled out**

Thoughts:

After we went through the study guide in the Alberta Learning booklet, one thing still stands out. The guide said that even if you have no clue in the slightest as to what the answer to a question might be you should still write something down because it will help you. I don't get it, how is writting something that is completly wrong down going to help you?

I had not realized how much we had honestly covered this year untill I saw the booklet of the learning objectives, all I can say is HOLY COW! It doesn't seem like we have covered that much. That diploma is starting to look a little overwhelming. With the help of all the worksheets we are going to get, and the study guide, I'm sure we will be fine. The study guide is going to be very helpful considering it contains a bunch of terms, technologies and disorders for the unit.

Insight:

So with the looming diploma and all the work put upon us it is really time to stick our noses to the books and get down to work. Refreshing your memory of everything we have learned is good thing but also a bit overwhelming. Before, it didn't feel like we really had alot to go and look back on and now when we do go and look back, we really have covered alot of stuff. After it being so long since we covered all these units I forgot how much detail there really is to the first unit.

Time now to head to the books and come out with ink on our noses!!

Megan's make-up blog for my second blog. Dec. whatever it was last friday- 3/3!

Well, on friday, I guess it was the 14th, we did... not very much.
We: Had a pop quiz :o boo...
Went through a power point on Hardy-Weinberg equations
Got a worksheet to do.
Honestly, that was all we did.

I think that the HW eqautions are a little confusing, but the questions that go with them are hard, worded so difficultly!!!

But i was wondering, what exactly does this (HW)have to do with anything, and will I ever need it?
Yeah, after lots of looking, i found that it is usefull to finding out how many people are carriers for diseases, which is imposible to tell from the outside. I probably won't ever need this again, but you never know.

November 26, 2007. Janelle Eslinger. 3/3.

What went down in class today:

1. What are barr bodies?


2. Marked the test from Friday on Mandelian Genetics.


3. Gene mapping in the note handout. Complete the questions at the end of the handout and reffer to pages 450 & 503 in the textbook.


4. Corrections for the Mandelian Genetics test are due on Monday, December 3. You have the opportunity to gain 1/3 of the marks you missed!


5. We also have a Quiz on Chapter 21 & 22 on Thursday, November 29.

Important terms and a summary of the material covered:

Linked Genes - are located on the same chormisome. Genes located on the same chromosome tend ot be transmitted together.

This helps explain the difference that occured when Morgan was breeing fruit flies. Crossing over, (a term learned in meiosis chapter) provides new combinations.

For example, imagine a man who has one chromosome with brown-eye and brown-hair genes, and another chromosome with blue-eye and blonde-hair genes in his cells. Usually, his sperm cells will have either brown-eye and brown-hair genes, or blue-eye and blonde-hair genes. But if crossing over occurs, the man will produce one sperm cell with brown-eye and blonde-hair genes, and another with blue-eye and brown-hair genes.

The crossover frequency is another important term to consider. A crossover value of 1% indicates that the genes are close to each other. A crossover value of 12% indicates that the genes are much farther apart. The greather the crossover frequency of crossover, the greater the map distance. (Map Distance - refers to the distance between two genes along the same chromisome).

What are the maps like that are being made now?

The genome's cartographers are now making maps that combine features of both genetic-linkage and physical maps. As mapping techniques advance, scientists try to create maps with more landmarks that are more closely, evenly, and accurately spaced. But in contrast to DNA sequencing, which has become increasingly automated, genome mapping still can only be accomplished by experienced scientists.

This website was really helpful for understanding gene mapping. http://www.genomenewsnetwork.org/resources/whats_a_genome/Chp3_1.shtml#chp3#1

What we learned in Biology 30 today (3/3)

We discussed are homework, this included>

Case Study on page 479:

In this activity you had to solve a murder mystery using genetics. A suspect witnesses that the murderer had freckled skin. They also found a letter opener which had blood on it, even though there was no cuts or abrasions on the victim. You are given the blood types of the suspects and if they are dominant or recessive to freckles.

You must find who did it using punnett squares and pedigree's

This is a great idea because you can what we learn in biology in a close to real life situation

Next we talked about the Pedigree studies work sheet we were assigned for homework...

Not much to say about that. Its just about all common sense, just remember the rules. (Which by the way are all on are biology data sheets)


We began notes on Chromosomal Theory----Most of it went right over my head because most of the focus was put on are upcoming test tomorrow.

For tomorrow genetic test it was mentioned to know this,

Know punnet squares
Know pedigrees
Know types of inheritance
Know how to do a test cross

Not really to excited about that.....

Andrea Grenier: Nov. 19th (3/3)

What we did:
We went over question #9 on P.483
We finished nothes on the law of independent assortment and probability calculations
We did an activity on dihybrid crosses by tossing pennies

Thoughts/Opinions about material:
During the activity, we labelled pennies and tossed them to show the probability of inheriting genetic traits. I liked this activity because it showed random patterns and it parallels to real life. In real life, the probability of inheriting certain genetic traits is random. What I didn't like about this activity is that you had to toss 4 pennies...96 times...twice!! And then write your result for each toss. Oh and I missed the last block of the friday before because I was getting a hepatitis A shot...So I had no clue about question 9, so I can't really relate to that...

Above and Beyond:

I like this Punnett Square because it shows really well the predicted genetic traits. I like the colors.
