Muddiest Point

My muddiest point is difference between depolarization and polarization and when each occur.

muddiest point

my muddiest point is where does the electrons come from between light independent and dependent cycles

Class on 2/24 and 2/25

Today in class we looked over the two plants of the day. The first one we looked over was the VENUS FLY TRAP. The second one we looked over was the BASEBALL PLANT.

We went over the 4 characteristics of the plant kingdom.

1. Eukaryotic

2. Photosynthesis, autotrophic, and contains chloroplasts.
3. Cell wall with cellulose2. Photosynthesis, autotrophic, and contains chloroplasts.

4. Multicellular

We also talked about the phylogenetic tree. The Green Algae and the Mosses have to live in moist environments due to the fact that they do not contain true - water conducting tissues.

We also went over our quiz.

Things plants need to survive.

1. CO2 for photosynthesis.

2. water for photosynthesis.

3. sunlight (energy)

4. minerals (nitrogen)

5. O2 for cellular respiration!

- Plant's mitochondria get glucose from photosynthesis.

Challenges for plants moving from water to land.

1. The ability to obtain water some way.

2. Prevent from dying due to direct sunlight

3. REPRODUCTION

NEXT SCRIBE WILL BE PETER FOX

Middiest point

My muddiest point is that I still do not understand the difference between Agnatha, Chondrichthyes, and Osteichtyes.

Muddiest Point

I kind of do not understand what co evolution and convergent evolution are.

Muddiest Point

Im confused about positive and negative feedback. Also the endocrine system.

Muddiest Point

My muddiest points are what happens in each step of meiosis.

Huntington's disease

Huntington's Disease is a disorder in which the nerve cells in certain brain parts are wasted. HD is inherited by parents. Huntington's Disease is a genetic defect that take place on chromosome 4. There are no known treatments yet for HD. The main goal is to slow down the symptoms. People with HD usually die within 15-20 years. The HD itself is a reason people die, but another common reason is suicide. There are 2 forms of HD. The more common one develops at the age of mid 30's and 40's. The more rare type develops at a young age. If the parents have HD there is a 50% chance that the child will also have it.

Symptoms

• Behavioral disturbances

• Hallucinations

• Irritability

• Moodiness

• Restlessness or fidgeting

• Paranoia

• Psychosis

  
  

  
  

11/4/11 Scribe

Today in class, we learned how to read a certain type of graph. Also we learned exactly how a T cell kills an infected cell and the process of it.

We also learned a little about APC

APC means Antigen Presenting cell.

Our homework is in the unit packet, pages 32, and pages 37-42 also to read 35.4

The next scribe will be SARAH

Muddiest Point

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

Scribe Post

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

My Muddiest Point

im still confused on the difference between ATP and ADP

Muddiest Point

For me my muddiest point is to study and actually get something out of the work and not just do it just to finish it. Also study on a regular bases instead of studying last moment

The Nature of Science

I enjoyed the first unit of science. I think that it was a great and fascinating way to start off the year. We also got a chance to work on labs which helped us get to know each other more. During the first unit, I have learned many new thing as well as old things. I learned new words such as; biosphere, biotic, abiotic, what levels of organizations are, and what an ecosystem is. Some of the things that reviewed was the different variables. The different variables were, independent, dependent, controlled variable, and control group. Also we reviewed on the outline of writing a hypothesis. Another thing that I reviewed was how to use a microscope. We learned how to form a conclusion. Also we learned the difference between qualitative and quantitative. The last thing that we learned about was organize and tell the difference between line, bar, and pie graphs.
