Give an example of (i) micelles system (ii) macromolecular colloid.

Explanation

To answer the question, we will provide examples of both a micelle system and a macromolecular colloid.

### Step-by-Step Solution:

1. **Understanding Micelles:**
- Micelles are aggregates of surfactant molecules that form in a solution when the concentration of surfactants exceeds a certain threshold known as the critical micelle concentration (CMC). They have a hydrophobic (water-repelling) core and a hydrophilic (water-attracting) outer surface.

2. **Example of a Micelle System:**
