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.

Which of the following statement is true?
A) PAM matrices are derived from an evolutionary model whereas the BLOSUM matrices consist of entirely direct observations. 
B) Because of BLOSUM matrices have less evolutionary meaning that is why the PAM matrices are used most often for reconstructing phylogenetic trees.
C) BLOSUM matrices are entirely derived from local sequence alignments of conserved sequence blocks, whereas the PAM matrix is based on the global alignment of full-length sequences.
D) BLOSUM matrices are more advantageous in searching databases and finding conserved domains in proteins.
