greater polar molecule. Water is more polar than pentane and pentane is less of a polar molecule than methanol when it comes to comparing the mixture of water/pentane and the mixture of pentane/methanol. When food dye was added‚ it was able to form a homogeneous mixture of food because the food dye was a polar molecule‚ which made it water soluble. The next part of the lab was spent observing the effect chain length has on miscible alcohol in water. The result in table 4 matches the hypothesis that the

Most other bacterial genera are easily decolorized by acid alcohol. Ziehl/Neelsen Acid-Fast Staining Procedure In later years‚ Ehrlich’s technique was improved upon by two microbiologists‚ Ziehl and Neelsen. Like Ehrlich‚ Ziehl and Neelsen’s procedure requires heat to force the primary dye through the cell wall. Another microbiologist‚ Kinyoun‚ developed a

Some of your cheek cells should drift off into the dye. 4. Throw the toothpick away. 5. Stand a thin glass cover slip on its edge near the drop of dye. 6. Slowly lower the other side of the cover slip until it covers the dye completely. Make sure there are no air bubbles. 7. Make sure the lowest power lens (the shortest lens) is in place over the stage

Calculation Process: The rate of respiration is calculated by dividing the distance that the drop of dye moved over 5 (period of time). For example‚ at 19 OC‚ the distance that the drop has moved after 5 minutes for the 3 trials are respectively 0.19‚ 0.10 and 0.13. The rate of trial 1 is then calculated by dividing 0.19 over 5‚ which is 0.0380 (shown above). For average rate of respiration‚ it is calculated by adding up all 3 trials of the same temperature and dividing the sum by 3. Additionally

The largest dispersion of Jews was in the 8th century before the common era‚ however most of the Jews in Split came during the 3rd-4th century Romaniote immigration‚ along with the Syrian and Iranian exiles. This formed a strong Jewish presence on the East Adriatic Coast. The East Adriatic Coast was a smart place to settle because of its location for economic trade‚ not to mention its mild climate and beautiful geography. Salona‚ Dalmatia‚ and Split are all prime examples of the settlement of Jews
