[1] To protect themselves from predators, members of the glass frog family (Centrolenidae) rely on a unique form of camouflage known as translucency. [2] While many animals use solid colors to blend in with their environments, these frogs possess gelatinous, see-through skin on their limbs and undersides. [3] When perched on a leaf, the frog's body becomes less noticeable. [4] This effect, researchers have discovered, makes it difficult for hunting birds and wasps to detect the frogs under natural lighting conditions.
The writer wants to revise sentence 3 (reproduced below) to provide the most specific, concrete visual detail that illustrates how the frog's translucency functions as camouflage.
*When perched on a leaf, the frog's body becomes less noticeable.*
Which of the following versions of the sentence best achieves this goal?
- When resting on a leaf, the frog’s limbs diffuse light and mirror the exact green hue of the foliage below, blurring the sharp outline of its body.Answer
- BWhen perched on a leaf, the frog's translucent tissue allows it to blend in with its surrounding environment to escape the notice of various rainforest predators.
- CPerched on a leaf, researchers found that the frog is less noticeable because the light passes through it.
- DWhen perched on a leaf; the frog's translucent limbs and body edges adjust their brightness to match the foliage.
