What is the most correct overall conclusion of this chapter?
Answer and explanation
Correct answer: Organisms give coordinated responses to stimuli through nerve signals, hormones, and plant chemicals
The chapter shows that organisms detect stimuli and coordinate responses through different control systems. Animals use electrical nerve impulses and chemical hormones, while plants rely mainly on chemical messengers and regulated growth movements. These mechanisms help organisms respond, survive, and maintain internal functioning. Therefore option A gives the most complete conclusion. Options B, C, and D deny established responses or reduce them incorrectly to digestion alone.
