Biology · Control and Coordination
Why do multicellular organisms utilize chemical communication (hormonal) in addition to electrical impulses for cellular signaling?
- 1Because chemical communication travels through the body much faster than electrical impulses.
- 2Because chemical communication can only reach cells that are connected by specialized nervous tissue.
- 3Because stimulated cells can release chemical compounds faster than an electrical impulse can be generated.
- 4Because electrical impulses can only reach cells that are physically connected by nervous tissue.✓
Correct answer
Because electrical impulses can only reach cells that are physically connected by nervous tissue.
