Question

assessment questions
which quotation best supports the concept that organisms use bioluminescence to defend themselves?
a. \when morning comes, the squid expels 95% of the bacteria from its light organ\ (paragraph 5)
b. \thus many fish are red in color because it makes them nearly invisible to other fish\ (paragraph 6)
c. \a potential predator may be startled by the sudden glow after grazing a jellyfish and leave it alone.\ (paragraph 7)
d. \this usually occurs in groups of male fireflies\ (partial text)

Explanation:

• Option A: Talks about squid expelling bacteria, not defense via bioluminescence.
• Option B: Discusses fish color for invisibility, not bioluminescence - related defense.
• Option C: Shows a predator is startled by a jellyfish's glow (bioluminescence) and leaves, directly supporting defense use.
• Option D: (Incomplete, but from context) Likely about firefly behavior, not defense.

Answer:

C. "A potential predator may be startled by the sudden glow after grazing a jellyfish and leave it alone." (Paragraph 7)
