The over-application of ammonia-based fertilizers is toxic to tomato plants; however, a 2014 study conducted by researchers in Spain found that transgenic overexpression of phosphoenolpyruvate carboxykinase and/or malic enzyme increased the tolerance of tomato plants to excess ammonia exposure. Provide a reasonable explanation for this observation.

The process consists of the following: A. The coconuts are preprocessed (the preprocessing method doesn't need to be represented on the diagram) to produce coconut milk and “dry" coconut oil. B. The coconut oil passes through an "Oil Heater" (fuel-type) before entering a reactor (open-tank, stirred). C. Methanol and a small amount of sodium hydroxide (NaOH, acting as a catalyst) are mixed together in a mixer (open-tank, stirred), and the resulting mixture also enters the reactor described in B. D. In the reactor (described in B), the methanol and coconut oil react to form biodiesel and glycerol. Two streams leave the reactor: crude biodiesel (also containing some water and residuals) and glycerol (also containing…

Dry Matter Calculations (Show your work) if corn is 88% DM (as-fed) and has 8% CP as-fed), what is the CP value of that feed on a DM basis? If corn silage has 30% TDN (as-fed) and is 35% DM (as-fed), what is the TDN value of that feed on a DM basis? An alfalfa haylage sample was determined to possess 55% moisture. If this sample has 60% TDN on a DM basis, what is the TDN value of alfalfa haylage on an as-fed basis?

Suggest a suitable reactor system (type, configuration, feed arrangements etc.) and operating conditions for each of the following sets of reactions to maximize the selectivity of species D. Derive the instantaneous selectivity equations for each sets of reactions considering two reactor temperatures (i.e. 100°C or 900°C). Make sketches of your reactor system to clearly illustrate your operation strategy. The reaction rates are in mol/(dm.s) and the concentrations are in mol/dm³.
