The BOD5 value of a waste-water feed stream to an activated-sludge unit is S0 = 300 mg/l, and the effluent is desired to be S = 30 mg/l. The feed flow rate is F = 2× 10^7 l/day. For the recycle ratio of α = 0.5 and a steady-state biomass concentration of X = 5 g/l, Use the following kinetic parameters:

Some given facts regarding effector molecules such as;

a) HC-toxin-induced plasma membrane hyperpolarization in guard cells causes massive K+ uptake and permanent stomatal opening

b) Xanthomonas, are proteins that target the plant cell nucleus and causes change in gene expression, called transcription activator-like (TAL) effectors bind to the host plant DNA and activate the expression of genes

c) Fusicoccin, a cyclic peptide, acts on the enzyme histone deacetylase in the nucleus, and may have a compromising effect on the expression of genes involved in defense

d) Gibberellins accelerate growth, resulting in bigger plants when compared with uninfested plants. The gibberellins produced by the fungi are identical to those produced endogenously by the plant

Which of the following combination is incorrect?
