How do worms use their chemoreceptors in their environment?

• A. To produce light for communication with other worms
• B. To detect and respond to chemical cues in their surroundings, such as food sources or toxins
• C. To generate electrical impulses for muscle contraction
• D. To regulate their internal body temperature

Answer: (B)

Verified step by step guidance

1. Understand the role of chemoreceptors: Chemoreceptors are specialized sensory cells or structures that detect chemical stimuli in the environment. They are crucial for organisms to sense and respond to their surroundings.
2. Relate chemoreceptors to worms: Worms, like many other organisms, use chemoreceptors to detect chemical cues in their environment. These cues can include the presence of food, toxins, or other environmental signals.
3. Eliminate incorrect options: Worms do not use chemoreceptors to produce light for communication, as they do not have bioluminescent capabilities. Similarly, chemoreceptors are not involved in generating electrical impulses for muscle contraction or regulating body temperature.
4. Focus on the correct function: Worms rely on chemoreceptors to detect and respond to chemical cues, which helps them locate food sources, avoid harmful substances, and navigate their environment effectively.
5. Conclude the explanation: The correct answer is that worms use their chemoreceptors to detect and respond to chemical cues in their surroundings, such as food sources or toxins, which is essential for their survival and interaction with the environment.
