- The label on Vodka says that it is 40% ABV (alcohol by volume). In comparison, red wine contains 10% ABV (alcohol by volume). From this information I can conclude that: a. the potatoes from which vodka is made contain more carbohydrates to produce alcohol than do wine grapes b. the yeast made to produce vodka must not be killed by concentrations of alcohol above 10-15% ABV c. the alcohol in vodka is concentrated by distillation after fermentation d. vodka is made by letting water evaporate after fermentation e. vodka has fewer calories in 1.5 oz serving than a 6 oz serving of wine.2. Imagine you have 3 different crystals and 3 agar gel plates (Agar is a gel used in microbiology preparations). The crystals and their molecular weight is given below. If you place same amount of solution into a hole made in your agar gel plate and wait an hour the crystals will diffuse (see figure 1). a. Methylene blue (molecular weight (MW) is 319.85 g/mol); b. Potassium permanganate (MW is 158.03 g/mol); c. Nigrosin (MW is453.5 g/mol) Explain possible explanations for the differences noted among the diffusion rates of the three chemicals.A flat (not spherical) tissue engineered skin (thickness 2.5 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The diffusivity of oxygen in the skin is 3.4 E-9 m2/s, and according to experiments that you’ve performed, you want to make sure that the concentration of oxygen in the device doesn’t fall below 0.06 mol/m3. (Below that concentration harms the cells.) The rate of oxygen consumption is -5.9 E-17 mol/[cell◦s]. What is the maximum cellularity (in cells/mL, three significant digits) that this tissue engineered skin can support?
