After purification of your favorite plasmid you use a spectrophotometer to find the concentration of your DNA and observe the graph below. Resketch by hand this graph on your answer page with exact axis labels and scales. Redraw the red line. Draw, in your estimation, the absorption spectrum of what is expected of a good DNA prep.

To determine the effect of two glass types and three phosphor types on the light output of a television tube, light output is measured by the current required in series with the tu to produce 30 foot-lamberts of light output. Thus the higher the current, in microamperes the poorer the tube in light output. Three observations were taken under each of the six treatment conditions and the experiment was completely randomized. The following data were recorded Phosphor Type Glass Type...
Modify the data for both Carnes and Kreuger to ... 1) Create a violently left-skewed data set for Carnes 2) Create a sweetly symmetric data set for Kruger that is leptokuretic (don't grade me on my spelling) Where ... the data sets have the same RANGE and similar MEANS 3) Create a third data set (Benson Mega-Diffusers) that is platykuretic but whose mean and range is not the same at the other two data sets. Carnes 3-Way Diffuser Airflow (ft^3/s)...

The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...
