Muddiest Point

My muddiest point is what animals are made of no matter what backbone, like I'm kinda confused on cartillage and stuff.

Muddiest Point

So I'm kind of confused on what the isolations mean, like why do they give us evidence for evolution?

Muddy Point

My muddiest point is how the estrogen and progesterone give feedback and kind of the basis of the menstrual cycle.

The grossest point yet

my biggest confusion is how to determine the difference between Sex linked traits and regular, and what you use for the punnet squares. I know for blood it's like IAIA or IAi but for sex linked traits is it X(letter for disorder) X   or Y if it's a male. Just need the whole thing cleared up a little.

Fragile X Syndrome

Fragile X syndrome is a common form of mental retardation. This occurs when the FMRI gene- which produces protein, lacks the process of making protein. Some of the signs and symptoms are as follows

•   People with this disease have an affected ability to think, reason, or learn because of an impaired intellectual function
• At a young age, physical appearance is very slim, light skin, not much hair etc. But as the child hits puberty in their teen years they start to develop adult traits such as a longer face or jaw.
• People with Fragile X syndrome are very stressful and become upset very easily.
• Kids who try and speak either stutter somewhat or can have very large problems speaking words at all
• Anything that makes a loud or unexpected noise can be heavily disturbing to people with Fragile X syndrome 

The gene FMRI is shown by the nucleotide triplet CGG which appears 6 to 50 times in an unaffected person. To detect if one has Fragile X syndrome they look for how many sequences of CGG you have and make sure it is in that range. If not they diagnose you with the syndrome.
While there is no cure or treatment, there are many therapies to get somebody through this disorder.
Putting the child through a special education class everyday is one option, and another is letting him/her be in a regular class to experience what it is like. There are also physical and occupational therapists as well as speech and behavioral.
This disorder is more common in males and about 6,000 to 10,000 people are diagnosed with it every year.

Me Es Scribe!

Today In our shortened class, after we checked in the homework on genetic disorder problems, we took a quiz on 14.2 which involved  disorders caused by individual genes which include Sickle Cell Disease, Cystic Fibrosis, and Huntington's Disease. The quiz also touched on Nondisjunction- which is an error that occurs during meiosis where the homologous chromosomes fail to separate properly.

After the quiz we went over the diseases that were caused by Autosomal dominant alleles (Huntington's disease) and Co- Dominant alleles.

At the end of class we worked with the laptops on a web quest about karyotyping and chromosomal abnormalities.

The next scribe is Jonathan

Muddiest Point

My muddiest point is the process after antigens go into the macrophage, the example Ms. Stein showed in class. I'm kind of confused on what all the different T cells are doing after that.

Da Scribe of Da Day!

So we started off today by getting our tests back and then went into some notes on INFECTIOUS DISEASES VS. REGULAR DISEASES. We also started the beginning of our new unit on diseases and learned about deadly pathogens that get inside our immune system and harm us, and also viruses. We were also introduced to the Disease of the Day in where we will be investigating a disease for homework every day, or usually every day. We then found out Ms. Stein is GOING TO HAVE A BABY! Congratulations Ms. Stein! We ended with a short video that we will continue next class that had to do with a doctor named Semmelweis that had to convince his other fellows to wash their hands!               NEXT SCRIBE IS Shaaaaaaaaaaaaaaaaaaaaaaaaaannnneeeeeeee.

My Dirty Point Of Muddiness.

My muddiest point is about enzymes. Like I know that they are catalysts with protein that speed up chemical reactions but can someone further explain this or like exactly what catalysts are?

Muddiest Point

Hi it's Michael and my muddiest point is Successions and like I understand that they are a change in the community over a period in time but i'm confused on the difference between primary and secondary and such that.

First Post

Hello It's Michael M and something interesting about me is that I can solve a rubix cube in about 2 and a half minutes. Something I am looking forward to is peer group and going to all the football games, and of course the thing i am very saddened for the future about is homework.
