Question

For a soybean oil extraction system, solvent: soy ratio is maintained at 0.5:1 (w/w). Original seed contains 18% oil (w/w). If the meal (soy solid) after final desolventization has 0.01 kg oil per kg oil free meal, then the effectiveness of the solvent (kg oil/ kg solvent) in the extraction process is

Explanation

Evidence for photosynthetic regulation indicates light harvesting and carbon fixation coordinate energy flow. Option NAT aligns with this, as it supports efficient energy conversion, reflecting standard interpretations in plant biology.
