What are stem cells? Stem cells are found in many places in the body. They are important because they can divide to make copies of themselves. They can also develop into different types of cells‚ for example skin‚ blood‚ brain and bone. Why is stem cell research important for Parkinson’s? There is currently no known cure for Parkinson’s. While medicines can help to manage the symptoms‚ they may only be effective for a certain period of time before side effects develop.2 Brain surgery can offer

The cell membrane is made up of fats‚ proteins‚ lipids‚ and carbohydrates‚ and is a permeable structure. However‚ this permeation is very discerning because it only lets certain things pass through it. The cell membrane has a layer of phospholipids with hydrophobic ends and hydrophilic tops. The “tails” are made out of phosphate‚ while the “heads” are made up of two strings of fatty acids. There are two layers of these phospholipids‚ called the “bilayer”‚ and the tips of each phospholipid are facing

Why do you think our school is good for your future plans andpurposes? A simple bridge truss was the first structure I ever analyzed . The simplecombination of beams that could hold cars‚ trains‚ and trucks over long spansof water fascinated me . Having the tools to analyze the loads on the trussfurther increased my interest in structures . I encountered the bridge in atextbook for my first engineering class . Knowing that the professor‚ Mr . John Doe‚ was a tough teacher‚ I asked himfor th

Define Stem Cells and give background information on them. Stem cells are a class of undifferentiated cells that are able to differentiate into special cell types. There are two types of Stem Cells: Adult Stem cells and embryonic stem cells. Embryonic stem cells come from embryos that are 3-5 days old. They are often taken from the umbilical cord. They are used more than adult stem cells. Adult stem cells mainly come from bone marrow. Their primary function is to maintain homeostasis by replacing

Cell Division Why must cells divide? To start it off‚ cells can’t keep growing forever‚ so when they reach a certain size they will have to divide. Cells divide for four important reasons; reproduction‚ growth‚ repair‚ and replacement of damaged or worn out cells. Most cells divide at least once during their life cycle and some divide divide dozens of time times before they die. There are three types of cell division. They are binary fission‚ mitosis‚ and meiosis. When cell division is

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

Have you ever wondered why the military and our veterans are important? I mean really thought about it. Yes‚ they keep us safe‚ but it’s that and so much more. Without them our country wouldn’t exist and we wouldn’t have the rights that we have now. They fought in past wars‚ the present wars‚ and will fight in wars to come. They are our reason for being here‚ alive‚ today. Without them we wouldn’t be here and the United States wouldn’t exist. The Revolutionary War is a war we can never forget even
