Question
While researching a topic, a student has taken the following notes: - Bioluminescence is the emission of light by living organisms. - This light is produced by chemical reactions in organisms' cells. - This behavior serves to startle predators. - Black dragonfish emit a steady red light. - This behavior helps them locate prey in deep waters. The student wants to emphasize a difference between the behavior of jellyfish and that of black dragonfish. Which choice most effectively uses relevant information from the notes to accomplish this goal? Choose 1 answer: (A) Black dragonfish emit a steady red light, which helps them locate prey in deep waters. (B) Both jellyfish and black dragonfish are organisms that emit light, which is produced by chemical reactions in these organisms' cells. (C) Jellyfish emit light to startle predators, whereas black dragonfish do so to locate prey. (D) Bioluminescence, the emission of light by living organisms, results from chemical reactions in organisms' cells. .

Answer
Jellyfish use light to scare away predators, while black dragonfish use light to find their prey.
Solution
The most effective choice to emphasize the difference between the behavior of jellyfish and black dragonfish is:
**(C) Jellyfish emit light to startle predators, whereas black dragonfish do so to locate prey.**
**Explanation:**
- **Option C** directly contrasts the purposes of bioluminescence in both organisms, highlighting that jellyfish use light primarily as a defense mechanism (to startle predators), while black dragonfish use it for predation (to locate prey). This directly emphasizes the difference between the two.
The other options either focus solely on one organism, highlight similarities, or provide general information without contrasting the two species.
**Answer:**
**(C) Jellyfish emit light to startle predators, whereas black dragonfish do so to locate prey.**
