This video will really help you prepare for the SAT writing portion and the guy brings up some interesting things I would not have thought of myself.(MUST WATCH!)

This is an extra credit essay I did for my Chemistry Honors class:
Women
in Chemistry: Ruth Erica Benesch

Chemistry
I Honors
Throughout
history men have dominated the science field. When one thinks of a famous scientist,
a male normally comes to mind; like, Einstein, Bohr, or even Hooke. Over the
past several decades though women have started to stake their claim on science
by making advancements in a variety of fields and working side-by-side with their
male co-workers. They may not be as well known, but they are part of our
present and future. One famous woman in science is Ruth Erica Benesch.
Ruth Erica (Leroi) Benesch fled to
England from Berlin in the late 1930’s during World War II to escape Anti-Semitism in Germany. While in
England she continued through her high school studies and upon her graduation
she was accepted at London University. While pursuing her degree she worked a
part time job where she met Reinhold Benesch, who she later on married. The couple
moved to the United States then entered graduate school in Chicago at Northwestern
University. After finishing her Ph. D, Ruth accompanied by Reinhold started a
research team.
Their
main focus as biochemists was the components of the blood specifically
hemoglobin. Hemoglobin is a “gas transporting protein molecule” that transports
oxygen from the lungs to all other parts of the body. Hemoglobin also helps
give erythrocytes (red blood cells) their red coloring. This is due to oxygen
rich cells. Hemoglobin plays a very important part in homeostasis by
controlling the amount of oxygen delivered to each organ or part of the body
that keeps carbon dioxide levels down.
When
the human body makes energy, it uses glucoses (sugars) and oxygen that then
releases carbon dioxide as a by-product. Now, Ruth and Reinhold Benesch
questioned how the hemoglobin knew where to transport the oxygen. They wanted
to figure out how the hemoglobin determined which location was more in need compared
to another. They devoted their time into this research and finally came up with
an answer. They compared hemoglobin to delivery trucks for oxygen and through
this analogy-their theory was birthed and proven correct.
The
carbon dioxide that is released after the metabolized sugar and oxygen molecules
form builds up in that area and this is like a giant neon sign for the
hemoglobin; telling them where to go. The higher concentration of CO2 (carbon
dioxide) in an area lets the hemoglobin “know” that more oxygen is needed.
Therefore- the hemoglobin goes to the sites with higher levels of CO2 present
then to the areas with less CO2.
After
their break through studies on hemoglobin the Benesches started to study
disorders dealing with the hemoglobin process. One of the leading disorders
that they studied was Sickle -Cell Anemia. Sickle-Cell Anemia is a result of an
abnormality in a person’s hemoglobin. Instead of having a biconcave shaped cell
the cell takes on a crescent and or sickle shape. This is due to a form of
hemoglobin referred to as Hemoglobin S. This
disorder is very serious and can cause a variety of problems for the persons
affected. Because of the bizarre shape of the cell it can not carry sufficient
amounts of oxygen to the areas in need and the cells are more fragile than
normal biconcave erythrocytes.
During
their studies Ruth’s husband passed, but she still continued with her work. Furthering
her biochemical research, Ruth started to look into compounds that could help
replace or substitute natural hemoglobin. This would be used to help those
affected by Sickle-Cell Anemia and other hemoglobin disorders. Unfortunately she never did finish her
research, even though she continued it until her retirement in 1996.
Ruth
Benesch proved to everyone that a woman could not just make it in the science
field, but be productive and help further our knowledge. She was able to work
with a male as an equal and made impressive steps in not only chemistry, but in
the medical field as well. The results of her research have helped to further
our possibilities of synthesizing hemoglobin to help those affected by the many
disorders. That is a name to be remembered.

The Truth...
Dear Reader,
The way that people lie is amazing to me. The entire concept is astonishing. By lying or simply “twisting the truth” as most guilty parties say, hurts others. You would think that after thousands of years and documented cases of this and their outcome we would realize there is no positive ending. Yes, you may get what you want for the time being, but it will not last. That lie, even an ever so small one, will be recognized for what it truly is in the end. Then what is left for you? Mistrust and the repercussions for your actions plus a reputation for deceit. Think of what you are about to do. Tell the truth no matter how bad it may seem and if that isn’t good enough than no one can say you did the wrong thing. If you rely on lying than you will come to use it more and more until the reasons why blur and you’re left not remembering what the truth really is.
Lying becomes your safety cushion. Something you learn to fall back on. Nothing good comes of lying. It has torn apart marriages, friendships, families and whole countries. This is said a lot, but it is a shivering hard cold fact; learn from the mistakes of the past and tell the truth. Not just to those you care about, but also that stranger you just met. You’re not going to be damned by God if you lie. I don’t believe in that, but there is one thing that I do and that is The Truth.
Yours,
S.
The Beginning...
Dear Reader,
As our society evolves we lose sight of the fundamentals of life. We are ever growing and always on the go, never stopping. Yes, many people today debate on this subject, such as the amount of fast food places everywhere and the obesity rate of our youth or even global warming. These are all feasible problems to discuss, yet not what this blog will truly be about. I mean to address those little things that we take for granted in our generation. The things that are so minute while meaning so much more. Our morals are rapidly diminishing leading to a futile life.
This is just the beginning to learning how to slow down and cherish what is really important. To realize those things that are missed and lost by the hustle and bustle of today’s expectations. Sometimes the things that you think matter the most to you are just temporary distractions, so think like a novice about the world and forget what you know.
Yours,
S.
