Muddy point!!

Hey yall so what is the roll of root hairs what do they do???

SCRIBEEEE

Hello people of 8th period biology! Sooo yesterday we started class with our last two commercial presentations (which were awesome!!!!!!). Then we went to our POD which were a baseball plant, and a venus fly trap. The baseball plant is very interesting because well it looks like a baseball! It grows in the desert, it is the type of plants that absorbs water and stores it (like a juicy steak). The venus fly trap is very cool, it makes a sweet lining of nectar to attract flys. When the fies come over and start eating the nectar the venus fly trap have six hairs, if two are touched with in twenty seconds of the fly landing on it, it automatically closes. After that we took a quiz on our plant reading. Then, we talked about our presentation project!

MUDDIEST POINTTTT

So are some fish not invertebrates and vertebrate? I'm confused with if some fish are and aren't and which are made of cartilage???

SCRIBEEEE!!! YAY

So this is Sarah! with me late scribe post..... Any who what we did in class on tuesday!First we started with going over our chart from 34.3 reading I believe haha. The chart was about Internal and external fertilization and development. External fertilization is when the eggs are fertilized outside the body of the egg providing individual. The requirements of external fertilization are; Large number of gametes, and water. Internal fertilization is when the eggs are fertilized inside the body of the producing individual. External development is the same as external fertilization except the child or children are developing outside the body. Internal development is the same as internal fertilization except it is when the egg providing individual is carrying the developing baby inside the body. We also talked about the goals for the male and female reproductive system. Some examples for the female reproductive system are producing eggs, developing the baby, providing nutrients for the child inside the female, etc. Some goals for the male reproductive system are producing sperm, successfully transferring sperm to the female, etc. Finally we finished our video about all types of animals producing babies like, whales, fish, baboons, and many more!!! Well thats all for now! (:

Genetic Disorder

Sickle Cell Anemia

Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disorder have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape. Symptoms include, fever, swelling of the hands and feet, pain in the chest, abdomen, limbs, and joints, nosebleeds and frequent upper respiratory infections, fatigue and shortness of breath (signs of anemia), irritability, jaundice (yellowish discoloration of the skin and eyes), delayed puberty (in young teenagers), severe joint pain, progressive anemia, Leg sores, gum disease, vision problems. Blood tests can determine whether an individual has sickle cell trait or sickle cell disease. Treatment goals for sickle cell disease aim to relieve pain, prevent infections, and manage complications. Antibiotics, usually penicillin, are commonly given to infants and young children, as well as adults, to help prevent infections. Pain relief medication ranging from nonprescription nonsteroidal anti-inflammatory drugs (NSAIDs) to opiods are given to control pain. Hydroxyurea is prescribed for patients with moderate-to-severe sickle cell disease to help reduce the frequency of pain episodes and acute chest syndrome. There has not been a method proven to prevent sickle cell disease. But by taking the correct precautions to health problems is showing patients to live longer. The expected life expectancy with sickle cell disease is 42 years old for males and 48 for females.

MUDDIEST POINTTTT

Hey ya'll my muddiest point is the pedigree with the family tree how do you figure it out if one parent has is one doesn't and its all mixed up? helpppp

Biology : Meiosis - cell division YAY!!!!!!

Why is my point in the mud????

Heyy ya'll so my problem is...... Specific and Non-specific Defenses!!!!!!! yayyyyy Yo class whats the difference????? I'm sooooo confusedddd!!!!!!!! please helppp meee!!!!

Point Of Muddiness!!!!!

Hiiiiaaaa!!!! It's SarahL!!!! YAY so my muddiest point is that i'm confused with the difference between G1 phase and S-phase it's hard!!!! HELP MEEEE! thanks ya'll!!!

Enzymesss!!!!!!!!!!!!!!!

Hey ya'll it's Sarah L here with your newest scribe post!!!! YAY!!!

So in our wonderful biology class today we did a.... LAB!!!! It was sooo much fun and very cool to watch!.

In our procedure we first started to heat water to the decided temperature for you group (my group was 100). Then we marked twon lines one for the catalase (which is an enzyme that speeds up the process of chemical reactions!!! Ooo Ahhh

When we were done setting up it was time for the dirty work... So we filled the catalase to the first line of the test tube and we placed it in our water at the correct temperature of course, then waited ten minutes for results.

After ten minutes we checked the temperature to record it, then we took the tube out and put hydrogen peroxide into the tube to the second line. Then, we waited twenty seconds for results and we recorded the bubble height.

In the end, most of the bubble columns got to four to seven centimeters except the temperature of 100 degrees celcius. Also. the average temperature for all of them was twenty degrees celcius to fourty degrees celcius.

MUDDIEST POINTTTT

hey guys! It's Sarah L here with my muddiest point, and mine is independent & dependent variables we go over this so much I just can't seem to remember which changes and which doesn't. PLEASE HELPPPPP.
