Following statements are being made regarding conditional specification –
A. The process by which cells achieve their respective fates by interacting with other cells.
B. the cell “knows” very early what it is to become without interacting with other cells.
C. The critical factors that control cell fate are present and differentially segregated in the cytoplasm of these cells.
D. a cell becomes is specified by the array of interactions it has with its neighbors, which may include cell-to-cell contacts (juxtacrine factors), secreted signals (paracrine factors).

An industrial waste-water stream is fed to a stirred-tank
reactor continuously and the cells are recycled back to the reactor from the
bottom of the sedimentation tank placed after the reactor. The following are
given for the system: F = 100 l/h; S0 = 5000 mg/l; mm = 0.25 h^-1 ; Ks = 200
mg/l; α (recycle ratio) = 0.6; C (cell
concentration factor) = 2; Y M X/S = 0.4. The effluent
concentration is desired to be 100 mg/l. The effluent concentration is desired to be
100 mg/l. If the residence time is 2 h in the sedimentation tank, determine the
volume of the sedimentation tank and cell concentration in the effluent of the
sedimentation tank.
