The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Sharks**: Begin by recognizing that sharks are a type of elasmobranch fish, which means they have a cartilaginous skeleton and multiple gill slits on each side of their head. This anatomical structure is crucial for their survival in marine environments. 2. **Sensory Adaptations**: Focus on the sensory adaptations of sharks, particularly their sense of smell. Sharks have specialized nostrils that are not used for breathing but are highly adapted for detecting scents in the water. 3. **Brain Functionality**: Note that a significant portion of a shark's brain, approximately 30%, is dedicated to processing smells. This indicates the importance of olfactory senses in their hunting and survival strategies. 4. **Distance Detection**: Based on their advanced olfactory system, sharks can detect blood in the water from a considerable distance. Research and studies indicate that they can sense blood from up to 1000 meters away. 5. **Selecting the Correct Option**: Given the options provided: - Option 1: 100 meters - Option 2: 1000 meters - Option 3: 2.5 kilometers - Option 4: 5 kilometers The correct answer is option 2, which states that sharks can detect blood from a distance of 1000 meters. **Final Answer**: A shark can detect blood in the sea from a distance of **1000 meters**. ---
