How is it that the intracellular level of `K^(+)` are higher than extracellular levels in animal cells ?

Explanation

To understand why the intracellular levels of potassium ions (K⁺) are higher than the extracellular levels in animal cells, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Ion Concentration**:
- In animal cells, potassium ions (K⁺) are found in higher concentrations inside the cell compared to outside. This is a fundamental characteristic of most animal cells.

2. **Cell Membrane Permeability**:
