Hey guys! So i am having trouble remembering what the cortex and the polar nuclei is? if you have any idea on how to remember them that would be great!

Thanks!

Hey guys,

So today in class we review photosynthesis and went over old homework.

Review:

• we reviewed the chloroplast during photosynthesis

Light Reaction

• chloroplast absorbs light and elections become energized
• water splits to produce H+ and O2
• electrons loses energy to form ATP ( ATP goes to calvin cycle)
• H+ and NADP forms NADPH ( carries energy to calvin cycle)

Calvin Cycle

• C02 is added to a 5 carbon sugar
• energy from NADPH and ATP used to make reactions
• produces sugar

Homework:

• review for quiz tomorrow
• finish the lab
• project due Wednesday 21st

the next scribe is: Jessica

Hey guys! I am having trouble with the difference between Platyhelminthes and nematoda. If someone can help that would be great!

Muddiest Point

Hey guys! I am having trouble with understanding punctuated equilibrium and convergent evolution. If anyone can help me understand them better that would be great.

Thanks!

Hey guys! so for my muddiest point, i am having trouble understanding what diagram D shows on the diagram of the menstrual cycle. i understand what it is showing but i dont understand why it is the way it is. If anyone could help me that would be great.
Thanks, Kelli

Hey guys!

For my muddiest point i am having trouble remembering which are dihybrid, incomplete and co-dominance problems. If anyone has any ideas to help me remember which is which that would be great. Thanks!

Fragile X

The gene for Fragile X is carried on the X chromosome because both males (XY) and females (XX) have at least one X chromosome, who can both can pass on the mutated gene to their children. Fragile X is when a father with the altered gene for Fragile X on his X chromosome will only pass that gene on to his daughters. If he has a son, he passes a Y chromosome on to his sons, which doesn’t transmit the condition. Therefore, if the father has the altered gene on his X chromosome, but the mother’s X chromosomes are normal, all of the couple’s daughters would have the altered gene for Fragile X, while none of their sons would have the mutated gene but can still have fragile X.

Signs and Symptoms

• Some degree of intellectual disability or learning problems
• Behavioral problems, such as difficulty paying attention and frequent tantrums
• Autistic-like behaviors, such as hand flapping and hand biting
• Delays in learning how to sit, walk and talk
• Speech problems
• Anxiety and mood problems
• Sensitivity to light, sounds, touch and textures

Detection and Diagnosis

Fragile X can be diagnosed using the person’s blood for the analysis of the FMR1 gene. This DNA test, available since the gene was first identified in 1991 can detect Fragile X in normal carriers and in those affected, but it cannot tell from that analysis if the child is or will be intellectually impaired or the severity of many of the symptoms.

Treatment

Standard treatment includes special education, speech, occupational, and sensory integration training; and behavior modification programs. Surgical correction of heart defects is sometimes necessary.

Life Expectancy

People with fragile X pretty much have a normal life expectancy. With having this though, they do sometime devolpe seizures which can effect their life expectancy.

Scribe 11/14

Hi everyone! so today in class, our UP pages 7 and 8 were checked.

OUR HOMEWORK:

1. Tribune Article due 11/21

2. UP pages 11-14

3. read 20.3 and do UP 9 and 10

Our lab today in class was a DNA activity. In the lab we built DNA models. In the first part we just needed to build one model that looked like this...

and when it is twisted it looks like this....

the next part of our lab had us split it in half and replicate the model. when you were done and you had 2 DNA models, it should look like this...

the next scribe will be Luke....

Hey guys! so for my muddiest point i need some help understating how bacteria has resistance to antibiotics. Is there something that can help me remember it? Thanks!

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....

this is the Little Blue Grass seeds This is the Indian Grass seeds

Hey guys! So for my muddiest point i am having trouble remembering the stages of interphase. Do you guys have any tips/tricks to help me remember them a little better? If you do that would really help me. Thanks!!

Hello everyone! Today in class we took notes and did a lab.

Homework:

Review for test quiz tomorrow, prelab, finish lab on Up pages 33-35 and remember to bring goggles to class.

Notes review:

Diffusion

• Particles are always moving


• particles move from areas of HIGH concentration to LOW concentration


• Particles move until EQUILIBRIUM is reached


• particles move passively

Osmosis

• DIFFUSION of WATER through a selectively permeable membrane.

Lab Review:
In the lab we did, we tested the diffusion of starch and glucose.

while setting up the lab in the beginning it should look something like this:

Afterwards it should look something like this:

The lab results were that there was iodine in the tube, glucose in the Becker and starch didn't get out.

The next scribe will be... Olivia!

Hey Everyone! For my muddiest point, my question is what is an autotroph? i just dont understand what it does? Can someone please explain it for me?

First Unit Reflection

I think that our first unit went pretty well to start off the year. The first unit started off sorta easy and a review to some. Although the quiz was not my best, i understand the material better now. I am exicted to see what come later in the year and what kind of experiments we get to conduct. Its been a good class so far! i cant wait to see what comes later in the year!
