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.

Hormonal interactions contribute to plant–insect herbivore interactions such as— ethylene, salicylic acid, and jasmonic acid. In particular, ethylene appears to play an important role in this context, what will be the effect of ethylene when is applied alone and when is applied with other amino acids?
a) ethylene applied together with JA it seems to reduces defense responses
b) Ethylene appears to applied alone to plants, ethylene has little effect on defense-related gene activation
c) when ethylene applied together with JA it seems to enhance JA responses or defense responses are significantly increased
d) Ethylene appears to applied alone to plants, ethylene has more effect on defense-related gene activation
Which of the following combination is correct about ethylene effects?
