My Muddiest Point

My muddiest point this unit is the difference between an artery and a vein. Thanks!

My Muddiest Point

Hey guys, it's Maggie! My muddiest point this unit is what the functions of the xylem and phloem are. Thank you!

My Muddiest Point

My muddiest point is how to distinguish the three different types of fish. Is there some mnemonic device that helps you?

Stuck In The Mud

Hey guys, it's Maggie.

I was just confused if the amount of a half life changes based on the substance that its on??

Evolution-Scribe

Hey guys! So sorry I forgot to do this yesterday. Yesterday in class, we started Unit 7 which is called, "Evolution". Evolution is defined as the changing of species over time. The amount of time that we are talking about is hundreds of millions of years. A very important man who brought this idea up was Darwin. His theory stated that species can change over time. This idea came up when he noticed how creatures could be different from one island to the next. This changing can either be beneficial to the species or can affect the species negatively. A negative effect can result in extinction because their new or old adaptions (characteristics) may not fit in with its environment. When most people think of the word evolution, the first thing that comes to their mind is that us as humans, evolved from apes/monkeys. But, the truth is that we share a common ancestor with apes. So to conclude, we all are apes.

Stuck in the Mud

My muddiest point in this unit is the different between FSH and LH. I know they are hormones but do they have different functions?

Marfan's Syndrome

Marfan’s syndrome is a disorder that affects connective tissue. Connective tissue helps support many parts of your body and holds all your limbs together. When a person has Marfan’s syndrome, their skeleton, heart, eyes, skin, nervous system and lungs are the most common body systems that can be affected. This disorder shows in many different ways. Some have mild symptoms and others have severe symptoms. Some severe symptoms include a collapsed lung, numb legs, a hernia, a heart murmur, or a curved backbone. Mild symptoms include having a long, narrow face, crowded teeth, nearsightedness, stretch marks, and snoring while sleeping. This disorder is caused by a defect in the gene that produces fibrillin. Fibrillin is a protein that makes up connective tissue along with other proteins. Fibrillin is also located on chromosome 15. All people are known to get Marfan’s syndrome. This includes: men, women, children, all ethnic groups and races. When someone thinks they have this disorder, their first step is to visit a medical geneticist. There they can determine if the person has the defected gene. There is not cure yet for Marfan’s syndrome but a lot of treatments can treat symptoms that occur. There are different treatments for each of the body systems. For example, if ones eyes are affected, regular eye check-ups are highly recommended because the doctor can catch and fix any eye problems that are expected. Usually, glasses can correct problems associated with Marfan’s Syndrome. People with Marfan’s Syndrome but do not realize, can die within 48 hours of having symptoms such as chest pains. But, if people catch it early enough and learn how to coupe with the disorder, people can live normal lives.

My Muddiest Point

Hey guys, its Maggie. My Muddiest Point in this unit is the pedigrees and how you can find the genotype of an individual on the chart if you don't know the parent's genotypes. Please help!

Stuck in the Mud

My muddiest point would be the difference between B and T cells. Help!

Bacteria

Hey guys, it's Maggie!

Today in class we went over quite a few slides on a powerpoint; mostly about bacteria. We learned the "Classification of Prokaryotes", which includes eubacteria and archeabacteria. We went over the three different shapes of bacteria. These include: bacilli (rod-shaped), cocci (spherical), and spirilla (corkscrew). Last but not least, we learned about binary fission and conjugation. Binary fission is when the DNA replicates and the cell divides in half. Cojugation is when a cell exchanged genetic material across a hollow bridge to another cell. At the end of class, we watched a movie that talked about fatal bacteria including anthrax. We have a quiz tomorrow so I hope everybody studies!

My Muddiest Point

My Muddiest Point in the cells unit was that I did not know the difference between the nucleus and the nucleolus and where they are located. If anyone could help that'd be great!

My Muddiest Point

Hey guys! So far in this chapter, my muddiest point was probably identifying each trophic levels on the chart. I did not understand how one organism could be 2nd and 3rd order consumer. Especially on the charts that had a lot of organisms on it.

Unit One

Hey guys! Well this first unit has gone by really fast actually. Something that was really interesting to me was the jumping beans. I've always wondered what made them have movement and it was really cool to learn what was actually inside of them. Also, its nice to really be hands on in class with experiments and such because last year we only did about 5 experiments so this unit has kept my interest unlike last year.

Interesting Facts

Hey guys, its Maggie. So, something that is interesting about me is that I love to snowboard and my favorite subject in school is math and science class. I'm also really organized and I also love to complete puzzles. It is interesting because most people absolutely hate math and science class and most teenagers are not organized. Something that I am excited for this year is meeting new people. Something that I am least excited about is getting a lot of homework. Alright well I hope this works!
