Which difference between hormones and nerve impulses is most scientifically accurate?
Answer and explanation
Correct answer: Hormones travel through the blood, whereas nerve impulses travel along nerves
The governing concept is the difference between endocrine and nervous coordination. Endocrine glands release hormones into the bloodstream, allowing chemical signals to reach target tissues, often with slower but longer-lasting effects. Nerve impulses are electrochemical signals conducted along neurons and are generally rapid and localized. Therefore option A gives the valid transport-based distinction; the words “always” in B and the claims in C and D are scientifically false.
