alleryWhat biological flow of charge is involved in nerves sending signals?
AFlow of blood cells
BFlow of charged ions
CFlow of bone salts
DFlow of air bubbles
Answer & Solution
Correct answer: B. Flow of charged ions
1. A biological example of current is the flow of ions in neurons and nerves.
2. Blood cells, bone salts and air bubbles do not carry nerve signals as current.
3. So ions are correct.
