Hormonal Control: Slower but Longer-Lasting Effects

Steps:

• Recall nervous control uses rapid electrical impulses via neurons for quick responses.
• Note hormonal control releases chemicals into bloodstream, which travel slower to target cells.
• Compare speed: nervous acts in milliseconds; hormonal takes seconds to minutes.
• Compare duration: nervous effects fade quickly; hormonal persist for hours to days.

Why C is correct:

• Hormonal control is slower due to diffusion through blood (slower than neural conduction) but long-term as hormones bind receptors and trigger sustained cellular changes.

Why the others are wrong:

• A: Hormonal control is slower, not faster, than nervous; long-term fits hormones but not speed.
• B: Nervous control is faster for short-term actions like reflexes, not hormones.
• D: Hormonal effects are long-term, not short-term, despite slowness.

Final answer: C
