Which of the following problems does the frequent deep sea diver organisms like whales may face ?

Options

A. Compression of tissues surrounding air filled cavities
B. High blood nitrogen levels
C. Lack of oxygen
D. All of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Problem**: The question asks about the problems faced by deep-sea diving organisms like whales. We need to consider the physiological challenges they encounter due to the high-pressure environment of deep-sea diving.

2. **Identifying the Risks of Deep Diving**: One significant risk associated with deep diving is decompression sickness, commonly known as "the bends." This condition occurs when a diver ascends too quickly, causing dissolved gases (primarily nitrogen) in the blood to form bubbles, leading to tissue damage.

3. **Comparing Humans and Whales**: Humans are not adapted to high-pressure environments, so when they dive, they can suffer from decompression sickness. However, whales and other marine mammals have adaptations that help them manage these pressures, such as regulating blood flow and slowing their heart rates.

4. **Recognizing Adaptations in Whales**: Whales have physiological adaptations that allow them to dive deep without suffering from the bends. They can manage nitrogen levels in their blood and prevent the formation of bubbles during ascent. However, if the pressure changes too rapidly, they can still experience decompression sickness.

5. **Evaluating the Options**:
- Lack of oxygen: This is not a direct cause of decompression sickness.
- Compression of tissues surrounding air-filled cavities: While this can occur, it is not the primary issue related to decompression sickness.
- High blood nitrogen level: This is a direct consequence of deep diving and can lead to tissue damage if the diver ascends too quickly.

6. **Conclusion**: The problem that frequent deep-sea diving organisms like whales may face is **high blood nitrogen levels**, which can lead to decompression sickness if they experience rapid changes in pressure.

**Final Answer**: High blood nitrogen level (Option B).
