Say true or false
i) The rate of breathing in aquatic organisms is much faster than that in terrestial organisms
ii) Phloem transports amino acids
iii) The rate of diffusion of oxygen in microscopic organisms in all directions is approximately equal to the rate at which oxygen is consumed in respiration.
iv) The cells and tissues and organs in the body of an animals work independently of each other
v) The endocrine system consists of ductless glands.

Explanation

### Step-by-Step Solution:

1. **Statement i**: "The rate of breathing in aquatic organisms is much faster than that in terrestrial organisms."
- **Analysis**: Aquatic organisms have a higher rate of breathing because they extract oxygen from water, which contains less oxygen compared to air. To meet their oxygen needs, they must breathe faster.
- **Conclusion**: **True**

2. **Statement ii**: "Phloem transports amino acids."
- **Analysis**: Phloem is responsible for transporting nutrients, including sugars and amino acids, throughout the plant. It plays a crucial role in the distribution of organic compounds.
