Hola clase de Biologia!

En clase dos con Mrs. Stein, hay muchas actividades. Primero, todos de los estudiantes vuelven los correciones de el concurso y UP 13-18. En clase los estudiantes miran los bandejas con los bacterias y escribir la informacion por los preguntas en UP 13-18. Despues los estudianted escriben el informacion por la enfermedad por el dia. El tarea es leer el capitulo 35.2 en el libro de text, el vencimiento es meircoles.

Hi bio class!

Today in biology class period 2 we did a lot. First everybody turned in the quiz corrections and reviewed the unit packed page 13-18. Then we looked at our trays with the bacteria we gathered on friday and put in a sealed tray to grow over the weekend. Using the information we got from the lab we further completed the unit packet page 13-18. The homework is to read and take notes on chapter 35.2 in the biology textbook. It's due on Wednesday.

Hey Everyone!

Today in class Mrs.Stein checked in our homework and gave us a stamp. She went over the answers with us before we discussed the disease of the day. First, we finished Schistosomiasis from yesterday. This disease is vector born and associated with snails. It affects the urinary system. The disease of the day was Influenza. It is caused by a RNA virus. Since the flu is a virus the best way to treat it is to prevent the spread of it.

At the end of the day we set up two labs that we will be doing on Monday. In the first lab we tested three surfaces. We then swabbed the cue tip on its proper quadrant on a dish. On Monday we will be looking for bacteria in these quadrants. In the second lab we put three antibiotics in the agar. We will observe the effects of the antibiotics.

Homework!

Hey !

Today we showed Mrs. Stein our homework and then got a spider stamp on our NEW stamp sheet! We then discussed section 20.3 and filled out a detailed double bubble map combining the classes homework into one map. After this we reviewed, before finally taking the quiz. After the quiz we then went over the 3rd Disease of the Day.

^^This is the double bubble map the class put together. Everything on the left(green) is what is specific to Bacterial Disease, and everything on the right(orange) is what is specific to Viral Disease. Everything in the middle(red) is characteristics that both types of diseases share. We also gave a list of specific types of Viral diseases, and specific types of Bacterial diseases too.

Viral:

• influenza
• HIV
• Herpes
• all kinds of pox

Bacterial:

• Cholera
• Strep throat
• Meningitis
• TB
• Clamydia

We reviewed anything anybody had questions on and if you still don't understand any of these concepts, watch this! :)

After the quiz we reviewed a little bit about the disease of the day, but we didn't get far because of rushed timing. The disease of the day was Schistosamiasis. Schistosomiasis is a vector born disease that is transmitted by snails.

We didn't get time to completely finish up this idea but hopefully we will tomorrow!

Homework for tonight:

• UP 12

Hope this helped with anybody's understanding! See ya tomorrow ( :
THE NEXT SCRIBE WILL BE.. SAM!

Bacteria!!!

Today we discussed BACTERIA!!! Here are the notes from class...

Bacteria Notes 10/26

View more presentations from Deb.

We also did our DISEASE OF THE DAY! Cholera is a bacterial disease that causes terrible diarrhea. The bacteria attacks the intestine prevent it from absorbing water. The result in the individual will die of dehydration within a matter of days. The disease is spread by contaminated water and is more common in parts of the world with poor sanitation. Fortunately, we have antibiotics that can treat cholera if they are administered early enough!

After our discussion of bacteria, we began a video on bacteria. It is important to remember that not all bacteria are pathogenic. Many bacteria perform countless useful tasks for us. Bacteria are used for food production, they aid in our digestion, and they play an important role in the ecosystem.

Remember... bacteria are EVERYWHERE! There are more bacteria in your body than there are cells in your body! They are tiny and they reproduce very quickly.

OUR NEXT SCRIBE WILL BE KRISTINA R

One thing we talked about in class today was Epidemiologists (just incase anyone didn't catch this Mrs. Stein was going to be an Epidemiologist but instead she is here with us!)(An Epidemiologist is a person who studies infectious diseases.) The first Epidemiologist was a British man named John Snow. In 1854, whenever someone got an infectious disease they thought their god was putting a curse on them. But John Snow did not believe this and wondered why the disease was spreading. He made a map of his town and traced the infectious disease to the Broad Street pump, and figured out that the virus was spreading through the water.

Another thing we went over in class today was the correct answer for the lab we did about the infectious disease that went around the school by various people. Here is the correct answer:

Mr.Paek

(science class)

Heather

(drama club)

Ed(carrier)

(bus 37) (bus 37) (math class)

Mr.Wegley Laura Mrs. Dillion

We also talked about some ways to prevent from getting an infectious disease. Some ways are paying attention to your surroundings, carry around Purell, don't share drinks, and most importantly, wash your hands after you use the bathroom.

What is a VIRUS?

-may be pathogenic

-may spread quickly

-NOT a cell

-made out of protein and genetic material

-not living!

-parasites rely on a cellular(they attack cells themselves)host to exist and replicate

-genetic material is not in nucleus(DNA or RNA)

-do not metabolize (use energy) or respond to stimuli

-consist of nucleic acid surrounded by a protein coat called a capsid(protein all viruses are made of)

-genes are expressed by using the machinery of the host they infect(gene expression=making proteins

Viruses come in a variety of shapes:

1. Bacteriophage

2. Tobacco Mosaic Virus

3. Influenza Virus

SORRY THIS POST TOOK UP SO MUCH SPACE!

Extra credit

Over the weekend, i went and i did the extra credit. For the extra credit, i went to the tyner interpertive center in the glen and i collected two types of grass seeds. The types of grass seeds i collected was Indian Grass and Little Blue Grass seeds. While i was there i learned alot and collected a lot of seeds. I learned that orchids can grow in the praire!

This is the Little Blue grass

This is the Indian grass

When the seeds were collected they looked like this....

Class of 10/

     In class today, we talked about the deseise of AIDS. AIDS stands for Acquired Immune Deficiency Syndrome. AIDS destroys your body's ability to fight viruses by weakening and even destroying your immune system. The fist stage of AIDS is actually not called AIDS, but HIV. HIV stands for Human Immunodeficiency Virus does essentially what AIDS does just not at the same speed, or power. You can get HIV/AIDS in three different ways: HIV positive blood mixing with your blood, unprotected sex with a person who was the virus, or genetically at birth. AIDS is a problem through out the world, but especially in the continent of Africa, where an epidemic of AIDS is killing people left and right.
     

    

AIDS DESEISE ATTACKING T-CELL 

     AIDS kills people by destroying their T-Cells; an immune cell meant, and needed, to fight of deseise. Viruses that would be easily fought off, now can become deadly to the person infected. HIV/ AIDS is never technically what killed a person. It killed off the persons immune system, and then the person became sick to another virus, which they could not fight off, that killed them.
