 * 1) What are the 5 elements that make up DNA? ** Guanine, adenine, thymine, cytosine, and sugar phosphate. **
 * 2) What is the function of DNA from day to day? ** It can tell us about organisms and heredity. **
 * 3) Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell. ** They are twisted into a double helix shape, then wrapped around histones, and compressed in the nucleus of the cell. **
 * 4)  What was the purpose of using the cell lysis solution? ** This unraveled the DNA and helped allow it to become visible. **
 * 5) Why does the DNA become visible once the alcohol is added? ** The alcohol enlarges the DNA. **
 * 6)  If DNA is so thin, how is it that we are able to see it during this simple lab exercise? ** It has been enlarged to a more visible level. **
 * 7) Why is DNA referred to as your genetic fingerprint? ** Because the identification of everything that you are found in DNA. **
 * 8) Give some examples of how DNA is used everyday. ** In crime to identify a culprit. **

=Diaper Disection= We cut a square out of the diaper to separate and view the layers. We applied 25mL of water to each layer. The top layer of the diaper was a material resembling tissue paper. It held about 25% of the water we put on it. We expect its purpose is to keep the skin of the baby dry. The middle layer of the diaper was a powder substance mixed with what looked like cotton. It held 100% of the water that was put on it and turned into a gel. The purpose of this material would be to absorb all the liquid. The bottom layer of the diaper was a papery/plastic texture and held 0% of the water that was administered to it. This material was water repellant and we expect its purpose would be to keep liquids from leaving the diaper. We tested the total amount of water the diaper could hold. We added 25mL to the diaper at even intervals. The diaper held a total of 600mL of water. A disposable diaper takes 200 to 500 years to break down in a landfill. They are also one of the most common items of household waste that go into the landfills. They account for 4% of all solid waste. In households with babies, disposable diapers can account for as much as 50% of the house's solid waste. Disposable diapers also have an environmental impact on animals and wildlife. Because they contain Tributyl-tin (TBT), disposable diapers could cause hormonal problems in humans as well as animals.
