Today we went over and Reviewed Evolution and Half Lifes!

To review half lifes we answered a question on page 29 of our unit packet (question B) this is also a great source of reviewing for Half life problems for the test on thursday! We then went over some class notes which then led us to beginning and almost finishing our labs in which we had to measure an compare the Jaw width and the Diameter of the brain capacity of a 1.Gorilla 2. Australopithicus (Lucy from the bio day movie) 3. Human. While doing the lab we had to fill out one of the pages between 42-47 that asked us to compare all of the 3 skull structures. After that you had to compare the Jaws with the teeth and the animals pelvis's. The data helped us understand and compare how each kind of organism that developed from that one ancestor that connected apes and humans.

Homework-

1. Finish Up 42-47

2. Read 26.3 with Cornel Notes or Check My Understanding Strategy.

SCRIBE POST!!!!!!!!!

Today in class we talked a lot about Half Lifes.

Which is the time period it takes for a certain substance to decay by half.

We also went over a few half life problems which i was struggling with a lot and so were others in the Class.

To help incorporate our lesson with half lifes we did an M&M lab---------------->

in which we had to count out 100 M&M's and then place them into a cup and shake for 10 seconds and pour the M&M's into the paper plate and all the M&Ms with the M facing up were to be eaten and then we would repeat the process shaking the M&Ms and adding 10 seconds onto each time we shook the container. After we finished with the lab we were given the right to eat the M&Ms and then begin working on the

HOMEWORK-

Finish UP 31-32 Use LINE GRAPH! NOT BAR GRAPH!

AndyD's Muddiest Point

My muddiest point is on the difference between Darwin and Lamarks theories.

AndyD's Muddiest Point

Positive and Negative Feedback, What are they? Differences? Similarities? Thanks =).

Wolf-Hirschhorn Syndrome

Wolf Hirschhorn affects 1 in 50,000 new born babies. Wolf Hirschhorn is caused by the partial deletion of the short arm on chrmosome 4. (pictured below)

Wolf Hirschhorn is characterized as a person with a disappearance on one of the arms of chromosome 4. Physical features include: Intrauterine growth restriction, mental retardation, characteristic facial dysmorphism, microcephaly, earlobe anomalies and closure defects ( cleft lip, coloboma of the eye, and cardiac septal affects ). Wolf-Hirschhorn also causes the person to have seizures and to have dental defects such as missing teeth. However 85-90% of cases of Wolf- Hirschhorn Syndrome are not inherited they are simply caused during a mutation when the egg and sperm meet. However the disorder may be inherited by a parent with the same disorder. The life expectancy for someone with Wolf-Hirschhorn is about 25. The oldest person still living with Wolf-Hirschhorn syndrome was born in 1949. Currently no population is a risk for Wolf-Hirschhorn syndrome because it is so rare. To date there are no known treatments for Wolf-Hirschhorn Syndrome.

AndyD's Muddiest Point

My muddiest point is the difference between autosomal recessive and autosomal dominant and how they work.

Today in class we learned about Genetic Disorders!

We started out by BrooklynC stamping our homework stamp-sheet and then discussing the homework with our groups of 3. After everything was settled at the beginning of class we went over the homework as a class and went over the problems that were unclear to us. After the class discussion we took some notes on Probability, What autosomal was, and what sex linked was. Probability was one of the things we discussed as we went over our Pedigree homework. We discussed the chances of having male and female babies and babies with disorders.

We also made the probability ratio of males and females in our class and their siblings

(pictured below). Males on bottom females on top because for some reason the image turned out awkward.

Homework

• Up 51-52
• Read Chapter 14.2 in textbook.
• Quiz on Thursday on the Punnet Square w/ co-dominance and etc.

Today in class we learned about PEDIGREES!

In class we first started out by discussing our homework with our new seating chart and groups that Mrs. Stein arranged for us. After our discussion with our peers we went over the correct answers as a class and discussed any of the questions that were kind of weirdly worded and tricky. After going through the answers we got into more detail with Blood typing and sex linked problems, especially the hybrid blood types.

Please ignore the names mentioned in the Pedigree above..... However the main lesson of today was Pedigrees. What are Pedigrees? They a chart made up of family members from one generation continuing on till the current. Pedigrees are used to trace disease or a specific trait within a family. Males in the chart are shown as Squares, and Females are shown as circles. However people that are shaded in have that trait or disease the is being tracked, women however with a half shaded circle are carriers of the disease or trait and may pass it on to one of their children and so on.

HOMEWORK!

• UP 47-50
• Read Chapter 14.1 in the textbook ( no duh where else?)
• Quiz on how to solve all of the punnet squares and problems on how to find a genotype and phenotype ( codominance etc.), Pedigrees will also be on the quiz!

How DNA was discovered!

Heres a 20 minute video about how James Watson discovered DNA! Told from the man himself!

Today in class we reviewed Mitosis!

Since Today was a late arrival the class didn't have too much time for really anything, at the beginning of class we discussed the process of Mitosis. Mitosis- Is the process by which a eukaryotic cell separates the chromosomes in its cells nucleus to form 2 identical cells. After discussing the Mitosis we did an activity using a sort of flash cards with the steps of Mitosis on it. Over here -----------> is a picture of the correct order of the green flash cards and the steps of Mitosis.

H.W for today- U.P. 44-47

Today In Class We Conducted our Enzyme Lab Expieriments!

In the lab we conducted we wanted to see how temperature affected enzymes effect on making chemical reactions faster. Enzyme- A protein that speeds up chemical reactions that take place within a cell.

The enzyme used in our lab was called Catalase. Catalase is an enzyme that speeds up chemical reactions. Our lab was based on how our enzyme (Catalase) affected the bubbling of hydrogen peroxide when mixed with catalase in different temperatures. Each lab group/table was given a different temperature to test the affect of Catalase in their temperatures being almost boiling Hot and piping Cold! To see images of the lab please refer to another periods blog because I forgot my camera that day :(

AndyD's Muddiest Point

My muddiest point is the difference between density-dependent limiting factors and density independent limiting factors as i am very confused about the concept and when i try to understand it i mix it up. Anyone have any useful skills on remembering the difference? Help is appreciated! Thanks,

AndyD's First Post~Oprah!

This is my idol, the one and only Oprah Winfrey! The famous multi-millionaire talk show host who's generosity and words of wisdom have made her be known across the nation. Oprah grew up in a poor rural town of Mississippi, poverty stricken she and her family struggled through life and eventually moved to Milwaukee where she was raised as a teen. Oprah also experienced many hardships through her childhood claiming to be sexually assaulted at age nine and pregnant at the age of fourteen ( her son died in infancy). Oprah eventually became involved in broadcasting in high school which led her to begin her own talk show. Anyway, Oprah was also known as one of the most generous people in the world. What she gave away on her show and donated to others in need was unreal. My 6th grade science teacher that is in love with Oprah was a witness of all this. She and other audience members were brought outside the studio to a parking lot to receive brand new cars, from this you can tell that Oprah is a very generous and giving person. After many years the legendary talk show host decided to stop broadcasting shows, however she wouldn't leave all her fans behind like that. Oprah then started her own television network called OWN (Oprah Winfrey Network). The OWN network features a variety of shows but are nothing compared to a talk show with Oprah. As you can see Oprah is a very kind, caring, and generous person that likes to give to others things she never had while going through life.

Excited~ Meeting new people and learning new things, 1 step closer to being finished with school.
