Answer:
b. 3,2,4,5,1
Explanation:
3. The action potential induces an electrochemical process that causes release of the acetylcholine.
2. Release of acetycholine into synaptic cleft is down an electrochemical gradient, i.e through diffusion and not requiring energy input.
4. Acetylcholine then binds and activates ligand-gated ion channels of the muscle fiber to open up.
5. Sodium ions will flow into the muscle generation an action potential that will culminate into contractions.
1. The enzyme acetylcholinesterase will breakdown any acetycholine not needed in the synaptic cleft.
Answer/Explanation:
Chilli and Beans are two different groups of crops having different nutrient requirement for them to grow well.
Beans is a leguminous crop that can help fix nitrogen back to the soil after the soil nitrogen content has been depleted by crops that use up nitrogen in the soil.
So, one of the possible reasons why Sangay plants Chilli the first, and beans the next year could be to ensure optimal productivity, as beans would replenish the soil with nitrogen. Also, both crops have different nutrient requirement. Nutrient requirement for both crops vary.
