Nickel is essential as a component of enzyme:

Urease (B) is correct here. This is core MINERAL Transport: once you know the definition or pathway step, Urease is the clear fit. The wrong ones are A) Nitrate reductase; C) Nitrogenase; D) RuBisCO. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Micronutrients are required approximately in:

Answer: B) 100 mg/kg dry matter. For MINERAL Transport, remember the key idea and you’ll land on this option; the distractors usually swap cause and effect or confuse similar terms. Avoid: A) 1000 mg/kg dry matter; C) 10 mg/kg dry matter; D) 1 mg/kg dry matter. Name the process first, then pick the option that describes it — don’t reverse cause and effect.
