Why is the focus of DNA-sequencing efforts shifting from the genomes of different species to individual differences within species? A) The sequencing of all species of interest has been completed. B) to reduce ethical and social issues related to gene research C Assembly of whole genomes takes longer due to the complexity of new techniques. D Sequencing has become more affordable.

A batch of 1000 kg of oil with heat capacity C = 1.97 kJ/kgK and density Poi = 910 kg/m3 is to be heated from an initial temperature T = 15°C to a final temperature Tf = 150°C in a jacketed vessel. The heat transfer area of the jacket is 4 m2, and the overall heat transfer coefficient is approximately U = 500 W/m-K. Steam condenses in the jacket at a temperature of 200°C. Assume that the contents of the vessel are well mixed, so that the temperature of the oil is uniform. (a) Consider the steady state operation of the system where the oil in the vessel is kept at T = 150°C. Hot oil at Ty = 150°C is continuously withdrawn at a rate roil from the vessel, and cold oil at T = 15°C is continuously added to the vessel. What is the mass flow rate of oil that can be withdrawn from the vessel? (b) Now consider the case where the system is run in batch mode. What is the time required to heat the oil from 15°C to 150°C? Automatic air vent H Steam Steam heated king vessel Strainer Condensate
