Muddiest Point

My muddiest point is the neuron! I do not understand the differences between the three types of neurons.

Muddiest Point

My muddiest point is the difference between chordates and vertebrates. How can all vertebrates be chordates, but not all chordates be vertebrates?

Muddiest Point

I do not understand the "similarities of embryos, homologous structures, vestigal structures, and biochemical similarities"

My muddiest point is the difference between the embryo, morula and blastocyst. Thanks!!

Muddiest Point

my muddiest points are the meaning of autosomal and sex-linked. I know that they are opposites (autosomal is the opposite of sex- linked), but what do they really mean?

Blooms Syndrome

Blooms syndrome is an inherited birth disorder. People diagnosed with Blooms syndrome are very short and weigh very little when they are born. On average, they only reach about 5 ft at the tallest when they are adults. Blooms syndrome causes the affected to have a very different and uncommon face. They typically have a long narrow face, a larger nose, and a high pitched voice. Men that have Blooms syndrome are unable to produce sperm. The disorder is most common in central and eastern Europe. One third of the affected are Ashkenazi Jews.

The condition is inherited by the auotosomal recessive pattern. The parents that produce a baby with this disorder are typically both carriers of the recessive/mutated gene. But, this does not mean that the parents have the disorder, they are carriers, not the affected.

Many with this syndrome are more prone to being diagnosed with cancer and diabetes. Many have severe troubles with learning. They also have many infections to the ears, respiratory tract, and lungs during their infancy.

Sister chromatid exchange: left is normal and right is Blooms syndrome.

scribe for 11/8!

Today in class, we discussed our last disease of the day. The disease was lyme disease. The agent of this disease is bacteria. The vector of this disease is the mosquito. Then, for the rest of class we reviewed for the TEST TOMORROW. We went over the quiz we took yesterday, and watched a

few short clips to review. The review session for our disease and immunity test will be

tomorrow morning, so make sure you try to make it of you have any questions!

Also, don't forget to check out the muddiest points, and make sure you've posted your comments!

STUDY STUDY STUDY! Check the moodle page to review with animations that Mrs. Stein

has posted! Good luck tomorrow!

BreckM's Muddiest point

I am having trouble remembering the different types of T-cells. What are the different types and what do they do?

thanks!

BreckM's Muddiest point

I am having trouble remembering the difference between diffusion and osmosis. If anyone has anything to help me understand it better that'd be great!

Thanks.

Breck's Muddiest Point

The Point that I am mixing up a lot are the different names for the relationships of animals. I know that the 3 are called mutualism, parasitism, and commensalism, but I mix up which means which.

Class on 9/16!!

Today in class, we went outside for "lab 58". In this lab, we each got a marked off area of grass, and we searched for different plant populations within the marked off squared area. Then for homework, we finished the data tables and analysis questions. This was due on 9/19. Also, we continued to take data on our duckweed experimentt. We touched base with out groups to see how the research precess was going along. Presentations for the duckweed lab will be due on Friday 9/23, so make sure your group is prepared and ready to present next Friday! Lab 58 can be found in your bio lab book. Mrs. Stein has these in her cabinets, and the lab is in them. The other homework for this weekend is to read 4.1 in your book, and make a comparison chart on 6.2 and 6.4. An example for this chart can be found here: http://gbs-moodle.glenbrook225.org/moodle/file.php/4383/Ecology/Envrionmental_Issues_Comparison_Chart_2011.pdf

(but be sure you don't just copy and print it!)

Breck M's Unit 1 Reflection

Unit 1 of STS Biology was a great way to start off the year. I learned a lot of new information and reviewed some information. I refreshed my memory on the different types of variables, and learned a new way of performing labs. I also reviewed how to write a hypothesis and learned a new way to write them as well.

I learned about the "scientific method". I now know that the first step is to ask a question, and then to form a hypothesis and test that hypothesis. We also did a lab on Tetrahymena. I learned a lot of new information during that lab and also refreshed my memory on how to perform a lab. I also learned the parts of a microscope. I used to be confused on a lot of things with the microscope, but that was cleared up during this unit. I think this will be a great Biology class and I look forward to the the rest of the year!

Breck M's First Post- John Mayer

I have always loved John Mayer’s music and enjoy hearing about his rise into fame. John Mayer is an extremely talented artist, guitarist, and singer. He has had many popular and successful albums. His career started with his first album “Room for Squares” and then following with “Heavier Things”. Then in 2003, he won a Grammy award for best male vocal performance for his song “Your Body is a Wonderland”. Mayer started with a lot of acoustic rock pieces, but has now started to write and perform songs of the American blues genre. After his album “Heavier Things”, he released “Battle Studies”. This album is one of the more popular works. It has the hit song “Half of my Heart” with Taylor swift. Mayer was born and raised in Bridgeport Connecticut. When he discovered that music was his passion in life, he attended the Berklee College of music in Boston.

“Any Given Thursday” is a collection of live music that was put together from his concerts in 2003. The live version of all of these songs proves once again that Mayer is a truly gifted singer and guitar player. Some of his best work is when he is performing live. "Any Given Thursday" is also a movie of him performing live. Mayer's music is timeless and great for any occasion.

What am I most excited about?- Sport seasons, meeting new people, and going to school with old friends.

What am I least excited about?- The homework!
