Question

Which statement best explains why electrical signals in the body are often based on

ions?
Olons contain a single atom.
Olonic bonds are very strong.
lons can gain electrons.
Olons are charged particles.

Answer 1

Ions are charged particles, that explains why they have either a positive or negative charge. Since electrical signals contain charges, that also explains why they are often based on ions. Your answer would be D

Answer 2

lons are charged particles is the correct answer.

Step-by-step explanation:

Electrical signals in the body are usually based on ions because ions are charged particles.

They produce an electrical gradient, therefore electrical signals are transferred.

The electrical signals in the neuron occur because ions flow over the neuronal layer as the Ions are the electrically charged particles.

The body requires ions to transmit the electrical impulse along the nerves.
