The diffusion constant of oxygen through water is an important limiting factor in the size of organisms that do not have active transport mechanisms to circulate oxygen through their systems. The diffusion constant or oxygen through water is 8 x 10-10 m2s-1. one average, how long does it take for an oxygen molecule to diffuse 1 mm through water?

7. The blue dye used in blue food dye is Brilliant Blue (FD&C Blue 1). Blue food dye is water-soluble so the molecule must be relatively polar. The structure of the dye is shown below. Mark all the groups in this molecule that can participate in ion-dipole interactions. H3C o O=S=0 O=S=O Na Na HC O=S=0 0 Figure 4. Molecular formula for FD&C Blue 1, or Brilliant Blue, dye.

Cross Cultural Business Challenges Cultural Borrowing 1. How would you describe cultural diffusion? 2. How do cultures choose what to culturally "borrow" from other cultures? 3. Do only less developed countries borrow from more developed countries? 4. Give an example of cultural borrowing or diffusion that you've seen in the U.S. (or in your native country). 5. What's a custom you would like to "borrow" from another culture?

In this experiment, you will measure the rate of photosynthesis
in isolated chloroplasts using the dye 2,6-dichloroindophenol
(DPIP). The transfer of electrons during the light-dependent
reaction results in the production of H+. This H+ ion can reduce
DPIP, changing its color from blue to clear. The color can be
quantitatively measured with a spectrophotometer. However, in this
experiment, you will qualitatively analyze your data.
Write a detailed conclusion for your experiment. How did light
affect the time it took for...
