mudddddy

Hi everyone! It's Tessa N here. I'm confused on what the reflex arc is... can anyone explain it?

stuck in the mud.

hay guys it's TessaN. does anyone have a good way to remember the vascular bundles of monocots and dicots? Which one is spread out and which one has the bundles in a circle?

SCRIBE!

Hey guys! It's Tessa N heree. So today in class we found out that FRIDAY is Mrs. Steins last day! :'( but... we are gonna have a baby showerr party! So don't forgett to bring food... Haha anyways we started off by going over the plant of the day, the string of pearls, also known as senecio rowleyan. Then we continued to review transportation, roots, and monocots vs. dicots. Transportation is the process by which water moves up a plant and out of a leaf. We learned the structure of roots, such as the cortex, stores food. Monocots and dicots both have vascular bundles, however the way they are arranged is different. Monocots have parallel leaves, 1 cotyledon, multiples of three flowers, and have fibrous, multiple roots. Dicots have branched leaves, 2 cotyledon, multiples of four or five flowers, and have a taproot, or a big main root. We then ended class by working on our flower labs for the last 15 minutes.

mudddddiestttt .

Hey it's Tessa here. I need someone to help me think of a way to remember the types of invertebrates in a manageable way, so I can learn the information and not just remember it word by word.

no comprende. Ayuda por favor?

Hey guys! TessaN heree. So I pretty much understand everything, but I missed the day when we did lab 38 about evidence of evolution. So I just want to clarify what is the difference between homologous and analogous structures?

point de muddy.

hi everyone! TessaN hereeeee. I missed one day of class where we went over the menstrual cycle, so can someone just give me a summary of what happens and what hormones cause to happen and what the egg does? thanks.

dominance say what?

HEY YALL. ITS TESSA. what is the difference between incomplete dominance and co-dominance?? help please. (comment)

Gaucher Disease

Gaucher disease is a rare genetic disorder when a person does not have enough of an enzyme, glucocerebrosidase, that breaks down the fat glucocerebroside. People who have the disease do not have enough glucocerebrosidase, so it builds up in the liver, the spleen, bone marrow, and nervous system, that prevents the body from functioning normally. Gaucher disease is an autosomal recessive disease, meaning it is inherited when both parents have the disease. It it caused by mutations in a single gene called GBA, which lead to low levels of glucocerebrosidase. So, someone who has Gaucher disease inherits a mutated copy of GBA from both of their parents. The disease happens in about 1 in 50,000 to 1 in 100,000 people in the general population. The people at highest risk for the disease are people of Ashkenazi Jewish ethnicity. There are three types of Gaucher disease- type 1, type 2, and type 3. Type 1 is the most common, and the effects are bone disease, anemia, and a bigger spleen. Type 2 happens to babies and can result in an early death. Type 3 can cause spleen, liver, and brain problems, and the life span is to adulthood. The signs and symptoms of the disorder are bone pain and fractures, cognitive impairment, easy bruising, a bigger spleen, a bigger liver, fatigue, heart problems, lung disease, seizures, severe swelling, and skin changes. Gaucher disease is diagnosed by a variety of tests- blood test, MRI, CT, X-ray of the skeleton, and genetic testing. Enzyme replacement therapy is available as treatment, and so is bone marrow transplants. Adults with type 1 disease usually live a normal life expectancy, but most diagnosed children die before the age of five.

M3!0$!5 [SCRIBEEEE]

!שלום כולם
hahah hey everybody TessaN here! If ya'll didn't know what that means.. its 'hey everybody' in Hebrew. o and to everyone that didn't know I'm Jewish lol I don't randomly know Hebrew don't worry, it's like my second language.
alright so anyways today in class we were a little behind, but it's okay because we still got a lot done! First, we handed in our homework. Then we went over the answers for the quiz about MEIOSIS. After that, we went over the homework. The homework was about crossing traits using punnett squares and explained how the dominant gene is used over the recessive gene. If you have Gg, the offspring are the big G, because the 2nd allele doesn't matter. The genotype are the letters (XX GG gg Ss Yy) and the phenotype are the traits/what it looks like (tall, short, green, yellow) Then, with about 10 minutes left of class we started the face lab! Mrs. Stein was nice enough to let us choose our own partners, and whatever we didn't finish we did for homework.

2 TYPES OF IMMUNITY SAY WHAT ???

Hey guys its Tessa N!
alright, so I don't understand the difference between active immunity and passive immunity. When do both happen and what is their effect on the body ???
HEEELLPPPP

and the last scribe goes to...

Hii everyonee its Tessa N! WHOOOO LAST SCRIBE. (thisss is gonna be the best one yet nbd) Okay so, we started off class handing in our double bubble maps of bacterial disease VS. viral disease. Bacterial disease produce toxins and may be treated with antibiotics. Some examples of bacterial disease are staph, lyme disease,meningitis (hope i spelled that right) and strep throat. Viral disease may be treated with antivirals, cannot be treated with antibiotics, may lead to cancer, damages DNA, the lytic cell will burst, and it disrupts the cellular process by hijacking the normal function of cells.Some examples of viral disease are HIV/AIDS, influenza, polio, and smallpox. Bacterial disease and viral disease both evolve rapidly, attack and destroy cells, disrupt homeostasis, are prevented by a vaccine, are caused by pathogens, reproduce rapidly, and are preventable in the same ways. Thennn... we took about 5 minutes to discuss our muddiest points with our neighbors, talking about the things we were confused about from the homework. Then, we had about 10 minutes to ask questions for the quiz we were about to take. Finally, we took our quiz! We had about 20 minutes at the end of class. It was mostly multiple choice, with two fill in the blank, and two short answer questions. It was on all of 20, and section 33.1- mostly about viruses, bacteria and diseases. I hope everyone did great ! Welll... that's it! I hope I see everyone bright and early at 5:00 am tomorrow... lol i can't wait for the pep rally, it's gonna be great!(:

/\/\udd!3$+ P0!n+. H3LPPPP !!

Anyone on this site hiiiii its tessa. ok so i don't really understand the cell cycle... what does each cell look like? that big bird stamp sheet totally confused me haha, I made BenS do all the work. i've trieed so hard to memorize them but it just doesn't stickk... ANY ADVICE?

what is logistic growth? help!!!

Hey everybody! I still do not understand what logistic growth is. In my notes I have the definition, but it doesn't make sense to me. I understand that it grows, but what makes it unique? And does this affect the whole population of organisms?

reflections on first unit

Hey guys It's TessaN!

Okay, so I thought the 1st Unit was very intriguing and fun. I enjoyed observing the jumping beans. I found it very interesting when my group experimented temperature with the jumping beans, and found out that heat increases the number of jumps. The experiment and the whole unit helped me learn about the jumping beans.

Hey!

hey everyone, this is Tessa!

Something interesting about me is I really want to be on Broadway when I'm older. I love to dance and sing and perform in front of an audience. I am looking forward to all of the football games and school dances, and I am not looking forward to a busy schedule, with hours of homework where I don't have time to hangout with my friends. That's pretty much it... (: Bye guys, can't wait to post my next entry!
