How the mammals are adapted for expelling hypotonic as well as hypertonic urine according to the body needs?

Explanation

### Step-by-Step Solution:

1. **Understanding Urine Types**:
- **Hypotonic Urine**: This is urine that is diluted, meaning it has a lower concentration of solutes (like salts) compared to the body fluids. When the body is in a hypotonic state, it has excess water and lower salt levels.
- **Hypertonic Urine**: This type of urine is concentrated, containing a higher concentration of solutes. It occurs when the body is in a hypertonic state, indicating a deficiency of water and higher salt levels.

2. **Mammalian Kidney Function**:
- Mammalian kidneys are highly adaptable organs that can regulate the concentration of urine based on the body's hydration levels. They can either expel large volumes of diluted urine or small volumes of concentrated urine.
