Question

question 3 of 10
how are the nervous system and the endocrine system different?
a. the endocrine system cannot send over long distances.
b. only the nervous system can send information.
c. only the endocrine system can affect cells.
d. the endocrine system affects cells with certain receptors.

Explanation:

The nervous system uses electrical impulses to send signals quickly. The endocrine system releases hormones into the bloodstream. Hormones in the endocrine system bind to specific receptors on target cells. Option A is wrong as endocrine signals can travel long - distance. Both systems (nervous and endocrine) can send information (so B is wrong) and affect cells (so C is wrong). Only D correctly describes a difference: the endocrine system's specificity based on receptor - hormone binding.

Answer:

D. The endocrine system affects cells with certain receptors
