generally speaking, how is the endocrine system different from the nervous system? more than one answer may be correct.
the endocrine system sends signals to one cell at a time.
the nervous system is able to respond more quickly to a stimulus.
the endocrine system only uses electrical signals.
the nervous system is able to stop responding more rapidly once a stimulus ceases.

Explanation:

• The endocrine system sends hormones through the bloodstream, which can affect multiple cells. So, the statement "The endocrine system sends signals to one cell at a time" is incorrect.
• The nervous system uses electrical impulses (action potentials) which are fast - acting. The endocrine system uses hormones which are slower. So, "The nervous system is able to respond more quickly to a stimulus" is correct.
• The endocrine system uses chemical signals (hormones), not only electrical signals. So, "The endocrine system only uses electrical signals" is incorrect.
• Once a stimulus stops, the nervous system (due to the nature of its electrical and synaptic transmission) can stop responding more rapidly compared to the endocrine system (where hormones need to be metabolized). So, "The nervous system is able to stop responding more rapidly once a stimulus ceases" is correct.

Answer:

B. The nervous system is able to respond more quickly to a stimulus.
D. The nervous system is able to stop responding more rapidly once a stimulus ceases.
