The mean free path of an oxygen molecule is 2.0 × 10-5 m, when the gas is at a pressure of 120 Pa and a temperature of 350 K. The molecular mass of oxygen is 32.0 g/mol and the Boltzmann constant is 1.38 × 10-23 J/K, Avogadro’s number is 6.02 × 1023 molecules/mole, and the ideal gas constant is R = 8.314 J/mol · K = 0.0821 L · atm/mol · K. Assuming that the molecules are moving at their root-mean-square speeds, the average time interval between collisions of an oxygen molecule is closest to

Transformation in bacteria is a very useful method used by scientists to insert a plasmid into bacteria so that bacteria will produce a wanted product. A great example of this is insulin production. What is an easy test that scientists commonly use that indicates that transformation was successful?
