identify the correct statements regarding nervous and endocrine system communication methods.
□ cells of the endocrine system communicate using chemical signals.
□ cells of the nervous system communicate using chemical signals.
□ cells of the endocrine system communicate predominantly via electrical signals.
□ cells of the nervous system communicate predominantly via electrical signals.

Explanation:

The endocrine system uses chemical signals (hormones) released into the bloodstream for communication. The nervous system uses both chemical signals (neurotransmitters) at synapses and predominantly uses electrical signals (action - potentials) to transmit information along neurons.

Answer:

• Cells of the endocrine system communicate using chemical signals.
• Cells of the nervous system communicate using chemical signals.
• Cells of the nervous system communicate predominantly via electrical signals.
