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. jellyfish emit flashes of blue light. 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 black dragonfish emit a steady red light, which helps them locate prey in deep waters. both jellyfish and black dragonfish are organisms that emit light, which is produced by chemical reactions in these organisms cells. jellyfish emit light to startle predators, whereas black dragonfish do so to locate prey. bioluminescence, the emission of light by living organisms, results from chemical reactions in organisms cells.

Explanation:

We need to find the option that emphasizes the difference in behavior. Option C directly contrasts the purpose of light - emission for jellyfish (startling predators) and black dragonfish (locating prey).

Answer:

C. Jellyfish emit light to startle predators, whereas black dragonfish do so to locate prey.
