Sarah U November 2012

Friday November 16, 2012

One hot summer day when I was putting my little buzzing fly wings to work-GULP! I got swallowed up by a stupid, mindless, and mean human!  It all started in the mouth where I was almost got chomped on by teeth and whipped by a tongue.  Teeth crush food while saliva makes it one slippery mass.  The mouth was soaking with saliva because of the salivary gland (which produces saliva). 


I screamed for joy as I took a fun ride down the esophagus, passing the epiglottis, which covers the windpipe so food doesn’t get past it.  Thank goodness I didn’t get stuck! The peristalsis of the esophagus pushed me down to make sure that I kept going in my direction.


Screeching, I landed in a pool of stomach juice.  I put on my super suit protect me from the acid inside the stomach.  The acid helps chemically digest food. I waited as the stomach churned around me as part of mechanical digestion.


After a few hours, I was released into the small intestine.  I was tickled by tons of tiny villi, which absorb nutrients into the blood stream.  I was also splashed with bile and enzymes


In fly science class, I had learned that the path of food and the path of nutrients are two completely different things.  I wanted to experience both, so I created a duplicate of myself.  One me was absorbed into the bloodstream while the other me stayed in the small intestine. 


The me that was not absorbed by villi finished the path of food by sliding through the large intestine, down the rectum, and out the anus.  The large intestine absorbs water from the remaining food.  The rectum compresses the waste back into solid form.  The waste is eliminated through the anus.  The rest of me was carried to the liver after being absorbed into the bloodstream


The liver was huge! It was like a big factory.  The liver breaks down substances like medicines.  The liver also produces bile (a substance that breaks down fats) that is stored in the gall bladder until it is needed in the small intestine.  The pancreas also helps break down food by producing enzymes that are later released into the small intestine.


That is the end of my amazing story, but first lets get one thing straight.  I only survived because of my super powers.  Do not try this at home!

How Does Genetics Impact Your Life?


            Genetics can determine many things in my life. They determine my appearance, my personality, and my preferences. They carry down traits from their parents. That is why their offspring are alike to them. Genetics also can carry down diseases in families. They impact my life and yours more than you may know. Here is how they influence mine.

            First of all, genetics impact my life because it determines most of my appearance. Half of the genes (more…)

How Do Genetics Impact My Life?

Genetics determine who I am, what I look like, and what genetic disorders I have or will get.  It shows what I prefer and what tastes I like.  Genetics show why I am colorblind and why I like spicy foods.  My genes also show the reason to why I am brown-haired, hazel-eyed, and have light brown skin.

Genetic diseases like color blindness and downs syndrome are caused by the probability of a child getting two alleles for a disease if it is recessive or one or more alleles if it is dominant.  I am color blind.  (more…)

Harper E – How genetics impacts my life.

Tuesday May 15, 2012

Genetics impact your life by what you look like. Sometimes, your traits are not the same as your parent’s traits but it was from one of your ancestors passed down from your family tree. Diseases you’re predisposed to can be caused by genetics also. It could also impact you by your parents. Genetics make up every little bit that you are. It is what gives you blond hair and blue eyes; it is what makes you short or tall.

One way that genes can put a huge impact on your life is by (more…)

Ebola by Marina April 2012

Monday April 23, 2012

Ebola virus is a branch of viruses that originated in Africa.  All four types of Ebola are deadly and incurable.  So far, it is impossible to vaccinate against or cure Ebola.  This disease is a virus, so it can’t be cured with an antibiotic. 


Ebola is spread by all primates, pigs, and bats.  Ebola has no vectors, so all of these animals get sick from Ebola.  This disease is caused by one of four viruses called Bundibugyo virus, Sudan virus, Tai Forest virus or Ebola virus.  They are all different sub-types of Ebola, and they all do the same damage on mammals. 

After four to six days of being infected, the symptoms start.  Those few days are called the incubation period of Ebola.  Some of the symptoms are: a hacking cough, stomach pain, fever, vomiting, red eyes, bleeding rashes in and outside of your body.  And those aren’t all of them.  Most of your skin, along with your muscle tissue will fall off.  This results in you vomiting up the black, infected remains of your organs.


Being in any physical contact with an infected person’s blood or bodily fluids will make it very likely for you to also be infected with Ebola.  If you’re a doctor and you were taking blood tests of an infected person you would most likely get Ebola too.  Luckily for most people, Ebola does not spread through the air, so you probably(emphasis on probably)won’t get any version of Ebola if you don’t get in contact with blood, mucus, sweat or other bodily fluids of an infected person.

Ebola virus used to kill people off so quickly that it didn’t spread out of Africa.  Now, due to fast air travel, the disease has spread to different places all over the world.  There is no vector for Ebola because it is so deadly, instead, pigs, bats, rodents, and primates all suffer and 90% of them die.

Malaria – by Brandon P. 2012

Wednesday April 4, 2012

Malaria is a disease common in many African places.  It is a wide-spreading disease that African-American children can often get.  Malaria is caused by an Anopheline Mosquito (female mosquito).  Malaria develops in the gut of the mosquito and it passes into the human through the mosquito’s saliva as it is biting and sucking a human’s blood.  The Plasmodium then travels to the human’s liver and then is distributed into the bloodstream.  The disease then begins to break down you red blood cells one-by-one. 


Plague – By Tyler W. February 2012

Tuesday April 3, 2012


The plague was an infectious disease or so the people of the Middle Ages thought when the first outbreak happened.  The plague killed one fourth of the people in Europe in mid 1300s.  After that there were more out breaks all around the world.  This disease is a deadly, and can kill you in one week. There are three types of plagues: septicemic, bubonic, and pneumonic. Each of these is all different.  All of the three diseases are caused by the rat which is transmitted by the flea.  The real term for the disease in the rat is Yersinia Pasties.


Chicken Pox – by Peter K. February 2012

Tuesday April 3, 2012


Chickenpox is a disease that spreads fairly easily. Caused by the varicella virus, chickenpox’s symptoms start 1-2 days before a rash appears. There is no known vector for this illness. Sore throats are often the first signs of chickenpox. This may be accompanied by fevers and headaches. The infamous rash of chickenpox (red spots)   constantly appears for up to seven days. These spots can blister and crust over all in 2 days.


Breast Cancer – by Ashby B. February 2012

Tuesday April 3, 2012

“About 1 in 8 U.S. women (just under 12%) will develop invasive breast cancer over the course of her lifetime.” 1  There are many questions about breast cancer that we ask ourselves like what causes this disease? What are the symptoms?  How is this disease spread among humans?  And how is this disease medically treated?  We need to know the answers because if we don’t then we might be more likely to get it.


Jenna W’s: Cell Analogy to a Restaurant Kitchen

Thursday March 1, 2012

Cell Analogies show that cells can be compared to everyday things. This comparison helps to have a more complete understanding of the different organelles. The example Analogy that was given during class was of a city. The Nucleus was the town hall, the the Mitochondria was the factory, etc. One Analogy that could fit a cell is a Kitchen in a Restaurant. A kitchen has all the analogies needed in order to compare it to a cell.


Joe G’s: Cell Analogy to The Universe

Thursday March 1, 2012

 A cell seems incomparable to anything in this universe.  But mabe the only thing one can compare it to is the universe itself.  Or, more specifically, a solar system.

In a cell, the mitochondria provide most of the power. This job is much like that of the sun, which produces energy for the rest of the solar system. The cell membrane, which protects the cell and controls what goes in and out, is like the atmosphere of a planet. An atmosphere will let light in, but debris will be burnt up. A cell membrane will let oxygen in, but will not let invaders through.
