What is the most correct comparative conclusion about nervous and hormonal control?
Answer and explanation
Correct answer: Nervous control is fast and definite while hormonal control can be slower and wider
Nervous control uses electrical impulses along neurons and chemical transmission at synapses, so it is generally rapid, precise, and directed to particular effectors. Endocrine control releases hormones into the bloodstream; their transport and action are usually slower, but they may influence several target tissues for a longer duration. Therefore option A gives the most accurate comparison. The other options reverse the speed relationship, exchange the transport routes, or wrongly restrict both systems to plants.
