In Neurospora, the mutant stp exhibits erratic stop-and start growth. When a female of stp strain is crossed with a normal strain acting as a male, all progeny individuals' showed stp mutant phenotype. However, the reciprocal cross resulted in all normal progeny, individuals. These results can be explained on the basis of

A. Uniparental gene contribution

B. Nuclear inheritance with concept of dominance

C. Sex link character

D. stp mutation may be located in chloroplast DNA

E. coli was continuously cultured in a continuous stirred tank fermenter with a working volume of 1.0 I by chemostat. A medium containing 4.0 g1^-1 of glucose as a carbon source was fed to the fermenter at a constant flow rate of 0.5 I h^-1, and the glucose concentration in the output stream was 0.20 g1^-1, The cell yield with respect to glucose YxS was 0.42 g dry cells per gram glucose. Determine the cell concentration in the output stream
