What are the main differences between b cells and t cells

Muddiest Point

My muddiest point is what the different types of T cells do

Muddiest Point- PatrykS

My muddiest point is i don't know what the difference is between bacteriophage and prophage and what they both do or mean?

Muddiest Point

Im still confused about the difference between the B cells and T cells

Interesting Game Related to Disease

http://www.addictinggames.com/strategy-games/pandemic2.jsp

This game demonstrates a lot of stuff that we learned in class and i found it really interesting how much i can relate to class when we learn some of the stuff that i saw in the game. In this game you get to a disease and try to spread it and you get to experience how it is spread, ect.

Today in class, we reviewed the differences and similarities between Bacterial and Viral diseases. After reviewing the differences, we took our quiz on Chapter 20, and section 35.1. The homework is UP 12. The disease of the day was Schistosomiasis.

Viral Diseases:

destroys cell by interfering with DNA

destroys cells by bursting them

NOT treated with antibiotics

Bacterial:

release toxins

treated with antibiotics

can be controlled

Similarities:

may be prevented by antibiotics

mutate, adapt, evolve

destroys cells

caused by pathogens

disrupts homeostasis

spread in similar ways

Today (10-25-11) in clase we handed in our Cancer paper stapled to our rubric. We also truned in the stampsheets and disscussed the lab we did yeterday. We started out the class talkng about What a virus is?

• made of proteins (caspids) and nucleic acid (genetic material): DNA/RNA



• NOT LIVING. Don't use energy, spread to forcing cells to make copies of them, and not cells


• Parasites: take over cells, require a host cell to exsist



• Gene Expression: making of proteins.

Then we talked about viruses reproduced by the lytic cycle or the lysogenic cycle

The picture on the right is a picture of a lytic cycle. As you can see virus first attaches it to the host (cell). Then releases the virus into the cell and attack the bacteria. Then start to make new tail fiber and then bursts out to spread the virus throught the body.

The Picture on the left is a picture of both lytic cycle and lysogenic cycle

The picture here shows us that the virus in the lysogentic cycle is attaching itself to the host's DNA. Then the cell replicates with the viral DNA. Lastly, the DNA exits host and make new viruses.

The homework was to read 20.2 and do correll notes on the chapter.

Today in class 10/24/11 we took a reading check on section 20.1. We then started the who infected whom lab. This lab was about a new disease that was going around gbs and we had to find out the web of infection like a epidemiologist. A epidemiologist is a scientist who traces the spread of a disease.

Today in class 10/21/11 we watched a movie called Surgery - Semmelweis and Lister. This movie is about a scientist that figures out a reason why so many women died while giving birth. He noticed that more women died when people who performed an autopsy delivered the baby. Semmelweis came up with the hypothesis, If you do or do not perform autopsy, then the chance of a women dying while giving birth will or will not go down. Some interesting facts were it took 6 years for death rates to drop from 30% to 1% while women were giving birth.

Our homework is The Cancer Paper is due 10/25 and Read 20.1 and write 6 types of questions. Must give complete answers. Due 10/24

Today the class started a new unit disease and immunity. the first thing that was done in class was we had our first disease of the day. todays disease was AIDS. we had a disscusion about disease and shortly disscussed AIDS. We talked about the spead of disease then watched a video about child bed fever, it showed how the a man realized that if you washed your hands you were less likely to spread disease.
