Again, note the use of figurative language, in this case the simile of the drunkard.
At night, schools of prey and predators are
almost always spectacularly illuminated by the
bioluminescence produced by the microscopic
Line and larger plankton. The reason for the ubiquitous
(5) production of light by the microorganisms of the
sea remains obscure, and suggested explanations
are controversial. It has been suggested that light
is a kind of inadvertent by-product of life in trans-
parent organisms. It has also been hypothesized
(10) that the emission of light on disturbance is advan-
tageous to the plankton in making the predators of
the plankton conspicuous to their predators!
Unquestionably, it does act this way. Indeed,
some fisheries base the detection of their prey on
(15) the bioluminescence that the fish excite. It is
difficult, however, to defend the thesis that this
effect was the direct factor in the original devel-
opment of bioluminescence, since the effect was
of no advantage to the individual microorganism
(20) that first developed it. Perhaps the luminescence
of a microorganism also discourages attack by
light-avoiding predators and is of initial survival
benefit to the individual. As it then becomes
general in the population, the effect of revealing
(25) plankton predators to their predators would also
become important.
The passage provides an answer to which of the following questions?
选项
A、What is the explanation for the phenomenon of bioluminescence in marine life?
B、Does the phenomenon of plankton bioluminescence have any practical applications?
C、Why do only certain specimens of marine life exhibit the phenomenon of bioluminescence?
D、How does underwater bioluminescence differ from atmospheric bioluminescence?
E、What are the steps that take place as an individual microorganism becomes bioluminescent?
答案
B
