A parent population (P) is change into daughter populations (Q) which grow in habitats. After 1000 generations, the equilibrium frequency distribution of of the daughter populations is shown in the figure below. For reference, the vertical line represents the mean of the parent population. Which type of natural selection?

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. The tank is now aerated. In the presence of gas bubbles, the approximate relationship between ungassed power number (N_P)₀ and gassed power number (N_P)g is: (N_P)g =0.5 (N_P)₀. What maximum stirrer speed is now possible in the sparged reactor? Estimate the mixing time.
