Answer- They wrap around proteins and folds back on itself, then coils into a compact chromosome. Answer- To put together the DNA strands. Answer- The DNA is less soluble in alcohol. Answer- The reason is that there are many clumped together. Answer- It passes on traits for the next generation. Answer- Some examples of how DNA is used everyday is traits, diseases, and disorders. = DNA Replication Model = media type="custom" key="12481796" =Protein Synthesis Flipbook= media type="custom" key="12652434" =Genetics Infographics= media type="custom" key="13421390" =My Medaka Story Infographic= media type="custom" key="13793068"

Diaper Dissection Lab

First, we cut out a segment of the diaper that was 2 inches by 2 inches. Then we studied and tested each layer for its material and water absorbency. We put about 25 mL on each layer. The first layer was made of a cotton-like material and was very thin. When it was tested it did not expand but absorbed the water. Layer 2 was made of a cotton-like material as well, but it had little pellets in it that looked like salt. When water was poured on it, it absorbed the water but did not expand like we thought. Layer 3 was the same as layer 2, however it didn’t absorb the water as well. Layer 4 was made of a sort of papery/plastic-like material. When this layer was tested, the water didn’t even go through it. The layer had repelled the water. Next, we tested the whole diaper. We first poured 200 mL of water on it. The diaper absorbed all the water and started to expand. The middle two layers looked like snow/jelly, squishy material. We then continued to pour 200 mL on the diaper. This time it absorbed the water but was getting heavy and still expanding. The third time it absorbed and expanded but the jelly started to leak out the sides. The fourth time it started to expand out of the diaper. The bottom of it was cold but still not wet. Finally, the last time, the diaper started to leak a lot of water. We had predicted that the diaper would absorb all of the water and would expand. The diaper did exactly what we expected. The environmental effects of disposable diapers on landfills can be very bad because the material inside the diaper does not dissolve or dissipate it stays there forever. Disposable diapers are also harmful to the environment because of Dioxin- a by-product of bleaching paper and according to EPA, it is known to cause damage to the central nervous system, kidneys, and liver.
