Differentiate between polarized membrane and depolarized membrane.

Explanation

### Step-by-Step Solution:

1. **Definition of Polarized Membrane**:
- A polarized membrane is characterized by an unequal distribution of electrical charges across its lipid bilayer. One side of the membrane has a positive charge, while the other side has a negative charge. This charge separation creates a resting potential, which is essential for the functioning of neurons and muscle cells.

2. **Characteristics of Polarized Membrane**:
- **Charge Distribution**: Positive charge on the outside and negative charge on the inside.
- **Resting Potential**: The difference in charge creates a resting membrane potential, typically around -70 mV in neurons.
