Which example best shows long-term control by hormones?
Answer and explanation
Correct answer: Body changes during adolescence
Hormones are chemical messengers released by endocrine glands. Their effects generally begin more slowly than nerve impulses and may continue for a long period. Changes during adolescence, such as growth and development of secondary sexual characteristics, are regulated largely by hormones. The other choices are rapid protective reflexes or automatic actions, so option A is the best answer.
