 Why has C. elegans proven to be a useful model for understanding apoptosis?

#Section 3: Genetics, Cellular and Molecular Biology

  1. C. elegans does not naturally use apoptosis, but can be induced to do so in the laboratory.

  2. C. elegans undergoes a fixed and easy-to-visualize number of apoptotic events during its normal development.

  3. C. elegans has large cells wherein apoptosis is easily observed without the aid of a microscope.

  4. As C. elegans ages, its cells die progressively until the whole organism is dead.

A cylindrical stirred bioreactor of diameter and height 2 m has a Rushton turbine one-third the tank diameter in size. The bioreactor contains Newtonian culture broth with the same density as water and with viscosity 4 cP. If the specific power consumption must not exceed 1.5 kW m-3, determine  the maximum allowable stirrer speed. What is the mixing time under these conditions?  __________
